''' Please backup your wallet.dat file before doing anything if you are having trouble accessing your QT wallet. The wallet.dat contains your private keys for each address, without those you will probably lose access to your Ravencoin.'''
'''Symptoms:'''
=== Restore wallet ===
==== Quick restore guide ====
Same steps as [[#Wallet does not sync|Wallet does not sync]] just put back your backup wallet.dat instead.
==== Full restore guide ====
This guide assumes you are starting fresh on a new computer.
* Start by installing Raven-QT wallet follow [[Best_practices#General_wallet_guide|General wallet guide]] if needed, skip encrypt and backup for now.
* Once you have Raven-qt running and fully synced, quit raven-qt and wait for it to fully exit.
* Open your Data folder, the default location is shown below this guide.
* Move the wallet.dat that is already inside your Data folder (Raven) folder to another location ie. desktop, and put your backup wallet.dat here instead. If you used a memorable name for your backup wallet.dat we need you rename it back to wallet.dat now.
*Launch Raven-qt and you should see your funds available.
Windows: %AppData%/Roaming/Raven
Mac: ~/Library/Application\ Support/Raven
Linux: ~/.raven
Note that " ~/ " is the home folder for linux and mac, not " / " root.
=== Wallet does not sync ===
* Make sure you've got a safe backup of your wallet.dat file
* Make sure you are running latest version of wallet from github
* help > debug > console, and type
addnode electrum-rvn.minermore.com add
addnode rvn.satoshi.org.uk add
==== Archive Wallet does not sync guidance ====
The first thing to try is to re download the blockchain.
* Make sure you're running the latest version of the wallet
* Close raven-qt completely, wait for shutdown window to disappear.
* Open %AppData%/Roaming folder and '''move''' Raven folder to desktop.
* Launch raven-qt and wait for blockchain to sync completely, then shut down completely.
* '''Move''' wallet.dat from your old raven folder on our desktop into the freshly created Raven folder in %AppData%/Roaming/.
* Launch raven-qt, and all should be well.
There is a guide on the [https://ravenforum.org/topic/20/ravencoin-wallet-and-troubleshoot Community forum], and here [https://virtopia.ca/ravencoin-fixing-no-sync-on-wallet/ Fixing no sync].

=== Crash on start up ===
The first thing to try is to re download blockchain. Follow same steps as [[#Wallet does not sync|Wallet does not sync]]
There is a guide on the [https://ravenforum.org/topic/20/ravencoin-wallet-and-troubleshoot Community forum].
===Transaction stuck ===
Try deleting the downloaded blockchain, and resync.
===Extra amount of rvn went missing when I transferred coins out of the wallet===
Try from within the wallet:
Help / Debug Window / Console: and write
listaddressgroupings
This will list all your addresses and their balance. Check for the "missing" amount.
This appears to be a display issue that happens rarely.
=== Change data location ===
Registry location
\HKEY_CURRENT_USER\Software\Raven\Raven-Qt\StrDataDir
Or you can start raven-qt with the flag below, to have it ask again as per initial installation:
-choosedatadir
=== Transaction to large ===
When the wallet has too many small transactions to a single address, it can cause a issue.

== Mining ==
===All miners===
Symptoms:
====Crash on startup.====
Check if Antivirus/Windows defender has deleted your miner.exe file, check if the .exe file is still in your folder. Fix by setting an exception.
====Crash/reboot after some time====
Check the power limit for the cards, 65% - 85% is common. x16r algo spikes the power draw so we need headroom in available wattage. Remember that the TDP for a card is an average draw of the card and in short spikes the total draw can be much higher. This is why the GPU manufacturers recommends much higher watt PSU than the TDP listed wattage of the cards would otherwise suggest.
====Naming you Rig on the pool====
On yiimp type pools you can use the password field like:
-p c=RVN,TitanV
,a comma is used to separate arguments, do not use special character or spaces in your rig name. Other pools usually set name by WALLET.rigname like:
-u RT2r9oGxQxbVE1Ji5p5iPgrqpNQLfc8ksH.titanV
When troubleshooting it is helpfull to have pause at the end of our bat file, so you can see the errors from console.
ccminer -a x16r -o stratum+tcp://miningpanda.site:3636 -u RBjAZ4fgoXfMC1ujzs7XKreMxJAL1r9fhT.titanV -p c=RVN,titanv -i 20 -N 600
pause
====Suprnova gives error on launch====
Check that you have created a worker on their webpage and supplied a password.' -u LOGIN.worker -p x ',also check their getting started on rvn.suprnova.cc start page.
====Hash rate is changing/low====
This is normal as the x16r algo is changing 16 times in each block, determined by the last 16 bytes of the last block. We need to look at a 2-3 hour averages at least to get a better average hash rate to compare, try adding ' -N 600 ' at the end of your bat file, it increases the average reporting time (default is 30).
====Getting a lot of "rejected" shares====
A rejected share means 2 possibilities:
1. The submitted share was invalid (bad hash of good data). This is caused by a GPU error on your end.
2. The submitted share was stale (good hash of bad data). This is caused by latency or lost data over the network between you and the pool.
If you're tweaking your GPU a lot (customizing power/frequency/voltage/etc.) then try backing down a bit and see if you get less errors. You should also check to make sure connected to the closest pool possible (e.g., don't connect to a pool in Europe if you live in the USA).
===Nevermore / ccminer===
Symptoms:
====Crash on startup====
Check .bat file that name miner at the start is the same as the miner in your folder. Nevermore uses 'ccminer' 2.2.5 might be 'ccminer-x64'.
===Sgminer / Avermore===
Symptoms:
====Crash on startup====
try adding
--gpu-platform 1
or
--gpu-platform 2
Brianmct has a good Getting started wiki on [https://github.com/brian112358/sgminer-x16r/wiki/Getting-Started github]
====Long startup time====
First time sgminer starts it compiles a kernel for all the cards, it can take several minutes.
