Can someone evaluate this database error and help me fix?...
 

Ever since my database was restored (lost it last week), I have been receiving the following database error notification via email at roughly 2am nightly. FWIW, I was running 3.8.2 when the dbase crashed and the database was restored to a point where I was still running 3.8.1. Might this be part of the issue? The files on the site are for 3.8.2. I planned to upgrade to 3.8.3 since the database issues I had last week started when I upgraded to 3.8.2.

Anyways, on to the code...

Code:
Database error in vBulletin 3.8.1:
