Backup your wallet.
Delete everything in your %appdata% directory except wallet.DAT
Start qt, it should sync up.
Our wallet is no real different than any wallet out there, except for fluttercoin festuresets, but core coin mechanics are still there. It is forked from novacoin and we have applied fixes with regards to any issues related that would cause issues, including fixes for other pieces. We are cosntsntly following numerous coins and applying fixes that we see. 0.4.5.11 is our latest and most stable wallet.
Apologies for the issues you are having but wallet problems occur. This is why every time we do something the first thing is backup wallet, also dumpprivkey address, and print that out. Ask Cryptsy how many times they have to resync the btc blockchain, this software and technology is beta for a reason.
These problems can be resolved. I have only had one issue where we could not retrieve the addresses in wallet because of a botched encryption process. But again there was no backup to try.
