Headache!

Not because yesterday was raining and today is sunny, but because I have read forums and faq's for hours without solving my problem.

I guess I am not that lucky, thus I need a hand here, sorry for bugging you guys.

No modifications on my 1.3.9 zencart on Godaddy linux hosting since 5 months ago, and all of a sudden yesterday I got this both as a regular user and as admin, from more than one computer:

"
144 Table './min1022707533517/zen_sessions' is marked as crashed and last (automatic?) repair failed
in:
[select value from zen_sessions where sesskey = 'pi4i7h0e9i0nadn4kcmr90k324' and expiry > '1320824491']
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.
"

It happens pretty often on Godaddy I could see, that sites simply become unavailable for a while, I hope they don't get a habit to do this.

As I am a presumptuous person, I presumed it's their fault, and issued a complaint note a few minutes ago

However I have a little doubt, since entering FTP on my hosting I found things where I left them, so I am asking:

What the is happening, I have not modified anything, in months, it was all routine, and all of a sudden... 144 error (whatever that means)

Question, is there anything I can do to fix it from the backdoor?

Or should I keep pissing off the Godaddy personnel?

Thanks for the time,

Emil.
