Either properly upgrade, or don't run it on a production site, so revert to your backup. Good luck!

MY SUGGESTION TO U
IS TO follow the following steps

1. back-up ur database and files ** highly recommended
   
2. delete all mods
3. delete all styles
4. delete all of the original .php files
5. upload vb4
6. and upgrade

good luck
