I am on windows 8 64 bit and since I upgraded to new 0.8.994 (cool looking and different wallet - finally one that doesn't look like every other one).. I get errors and it crashes and closes. I removed all appdata but wallet so it could re-download chain but it just gives me a "System error: CDB(): can't open database file wallet.dat, error -30974" I believe there is a problem. All other wallets I own work fine.. so it's not me.. anyone else have this happen or have a fix?
[Update]
I removed my wallet.dat from the appdata and let it create a new address and download blockchain again.. then moved my wallet.dat back to replace one it created after the whole blockchain was reloaded.. and now it "seems" to be working again with my original wallet address...I shall keep eye on it.. just to let you know in case this happens to anyone else.. at least its not crashing any more.. this could be some kind of upgrade problem when installing and uninstalling newer versions of megacoin wallet software on Win8(64).

That sounds weird, I have never had any issues with it. When in doubt, backup the wallet.DAT and re-install everything. That usually seems to work for any coin.
