Your vBulletin (3.6.8) does not appear to be running the version that was downloaded (3.7.0 Beta 3).

Re-upload ALL the files from 3.7.0 Beta 3 package, overwrite all the php files and xml files that are currently on the server. Then, check your config.php file and add the missing variables from config.php.new file. Finally, re-run the upgrade script. It should fix the above issue for you.
