Has anyone found their windows qt client keeps crashing after starting ok and being left to run? widows says it stopped working and it closes.
Haha, that's what we've been talking about for a few pages.
Solution:
For anyone reading, his solution was correct. Obviously, backup your wallet before making any changes to it.
Create a new address. Send the balance (maybe break it into smaller payments if it's a huge balance) of your wallet to that address. Go to help->debug. Go to console. dumpprivkey youraddress. Copy that into a txt file. Backup that wallet and move it out of your appdata/roaming/sonicscrewdriver folder. Start wallet with no wallet.dat. Go to help->debug->console. importprivkey yourprivkey.
That should work.
edit: If that's too complicated and you're tech unsavvy, you can just send the coins to bittrex and then create an address with your supersonic 2.0 client and then send them to your new wallet address. Send a small amount to bittrex first to test.
