Problem with database in usergroups

[idnpros]

I think that after a friend installed a hack (thanks hacks i think its called) i keep having problems in the admincp when try to manage usergroups.

When i hit save, i get this error

Code:

Database error in vBulletin 3.5.4:

How can i fix this problem?

Also another small question. Is there a way to move all users from a usergroup to another?

Thanks in advance for the support
