Hey Guys,
I was able to replicate this problem on a friends Windows 7 install, it seems to be some MSVCRT dll's that are missing. So I spent this morning building a full static client. Which seemed to fix his problem, can you let me know if this is the fix for you guys.

PS: With these windows builds, I am using berkley_db 1.47.25. Which the original fast-coin is using a different version. So it could require you clean out your %appdata%/Fastcoin folder and leave just the wallet.dat in there.
