MySQL Error: Incorrect key file for table 'blog_usercss'

[محروم.كوم]

Tried backing up my database this morning and I'm getting the error below. Never had any trouble backing up before. Only changes made to the system since the last backup: Upgraded php (from 5.2.4 to 5.2.11) and mysql (from 4.1.22 to 5.1.37). Restoring the DB is not an option. IE: New users* Style* etc.

Repair table tool didn't fix it. Also* there are no records on the blog_usercss table.

What to do?

Database error in vBulletin 3.8.3:

Invalid SQL:
SHOW CREATE TABLE blog_usercss;
