vBulletin hack fix (Website Design)

I am using the "Forums arranged in Columns on Forumhome" hack on my vBulletin board.

So far, it has worked perfectly.

However, since I upgraded from vBulletin 3.6.5. to the latest version 3.7.2. patch 1, I cannot get it to work anymore.

I therefore need a vBulletin expert who can fix this problem quickly.

I do have a testboard with a backup of the pre-upgrade board (where the hack works) so files can be compared.
