Error in Mysql?

[Tri_3Dent]

For some reason, I got this error this morning:

mySQL query error: DELETE FROM ibf_sessions WHERE running_time < 1056123464 or member_id='2'

mySQL error: Can't open file: 'ibf_sessions.MYI'. (errno: 145)
mySQL error code: 1016

What is it saying here? It was working fine yetserday and all of a sudden, it came up this error.

I had that problem recently, too, and now it's happening again. It means that one or more rows in your table ar corrupted. Use repair table tablename. You'll lose some data, but it will start working again.
