Help! Unable to complete db restore in build 7013.

I have recently tried to update to build 7015 but it failed halfway through and rolled back. Then the SD server wouldn't start even though I ensured the stopdb.bat had been run before clicking on the icon to start sd.

We ended up re-installed sd, updating to build 7013 (this version was the one we last took a backup from) and tried the restore. However, at the end of the restore process we get the error shown in the attached picture. I have tried two different backup files but I get the same problem with each.

Please help me to fix this as when we start SD now we get no Requests listed. Problems and Changes seem okay.

Thanks for your time.
