Database error

[tinbin]

There is an error in my database and i can't find how come..
I didn't install any hack or modification for the last weeks...

The URLs in the mail also point to a wrong URL:
/forum/~awesome-/forum/index.php

It just has to be forum/index.php

Can anyone give me a clue what causes this error?
Here's the mail:
