b2evolution: How to clear evo_hitlog?

So, as Dave has pointed out, I'm having some problems with N.Q.B.'s MySQL database (You can see the error by highlighting the text at the bottom of this page). I've posted a lengthy comment to the b2evolution forum and hope that some of those clever bastards (specifically Françios) can help.

If anyone knows anything about MySQL out there, I'd appreciate you taking a look at my problem.
