Need help restored crash sql base

[bilten]

I need urgent help to solve my forum's base
I do not have a backup backup of a good database.
So I NEED to help someone who gets to mysql and knows vbulletin too.
To date, everything has been working normally, so I had some problems with the server and now I have this ****. Error
MySQL Error: Table './citroen_vbver2/vb_filedata' is marked as crashed and last (automatic?) Failed
I can not fix this error in the usual way. It does not help any repair of cleaning the counters I switched off all the plugins nothing helps, but I need the side of the forum because of the sponsors I NEED to do back.
Now I have saved this by turning off the CMS because otherwise I have a database error on www.domena.com if I turn off the cms for the time being, I just need to go back to the database.
Who can help me

That is complete error

Database error in vBulletin 4.2.5:

Invalid SQL:
SELECT SUM(filesize) AS size FROM vb_filedata;

Run a repair on that table:

REPAIR TABLE vb_filedata

You may need to run Repair on the table multiple times. If the query above doesn't work, you should contact your Hosting Provider to have the repair done from the command line.
