Database error

Yesterday I got this error when I try to send a Pm:

Database error in vBulletin 3.6.8:

Invalid SQL:

SELECT COUNT(*) AS total, folderid
FROM pm AS pm
LEFT JOIN pmtext AS pmtext USING(pmtextid)
WHERE userid = 556
GROUP BY folderid;

MySQL Error : Unknown column 'pmtextid' in 'from clause'
Error Number : 1054

And to make it worse I had a virus at my PC last week and lost all my files including a backup of my database , what can I do
