MySQL syntax error after install

[siicis]

Hello!
After install I got this error in debug mode:
##
While executing query "delete from `GIFAFFI2009`.2009_sessions where time<1247599382 and remember=0;" on Resource id #6

mySQL error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.2009_sessions where time<1247599382 and remember=0' at line 1
##
This error also is in login file.

That I need to do?

Sloved this problem: first character of table prefix MUST be char, not number. For example: a123_ ir good, but 2009_ is bad.
