Fatal Error - Help!

[jdsnitch]

Hello!   

Can anyone let me know what the following means:

While executing query "delete from `simplycl_gallery`.cpg145_sessions where time<1191548486 and remember=0;" on Resource id #6

mySQL error: Can't open file: 'cpg145_sessions.MYI'. (errno: 145)

It's kind of hard to fix the problem when I can't figure out what it is.  I don't normally go about fixing this particular gallery, so I'm not all that familiar with this sort of information.

Thanks in advance to anyone who can help!

If you search for "(error: 145)" you will find plenty of answers. However you chose not to.
