I had a quick look at your backup file, and the solution is simple.

Your datastore cache in the backup is corrupted. Upload tools.php from the do_not_upload folder of your vBulletin distribution to your admincp directory. Then point your browser to http://www.myboard.com/admincp/tools.php and run [Usergroup / Forum Cache] and [Options Cache]. Your problems should be fixed (not checked if there are more problems).

Make sure to remove tools.php after you're finished!!!


PS In your backup file you also have create database statements (for your main and for a test database????). In 90% of the cases it is better not to include create database statements when making a backup.
