Need Help !!!

I get this error each time when i try to post and also i have the Rpg Integration hack installed.

vbulletin version: 2.2.8

You installed the hack wrongly. Uninstall it. That hack is still beta as well, so it may still have bugs. Post in the hack support thread and see if the author can help.

And how i can uninstall the hack ?

replace all the hacked files with unhacked again...
