Can't login, database error

[TuxDK]

Hello everyone.

This morning I couldn't log into my SMF 2.x installation.
I keep getting this error:

"Please try again. If you come back to this error screen, report the error to an administrator."

I haven't changed anything, it was working fine last night.
I've checked database and everything seem to be working fine.

Anyone know a solution or how to debug it further?

Solved, members table had crashed.
