Account Server Hang

[MistyMai]

Ok so my private server used to work just fine, and I do not remember changing anything. But now I am getting an error when starting accountserver ("'Main database handler create failed, AccountServer hang!") And gameserver won't start either.
I have tried reinstalling MySQL Server and reattaching the databases, which changed nothing. And I've tried changing the IP's in the .cfg files to "(local)". Accountserver and gameserver did work like this, but I could not get group- and gateserver working.
Any suggestions on how to fix this?
