Need help with correctly uninstalling a mod

[apokphp]

The vbprojects light version doesn't seem to be supported (so I don't expect much help in that thread). If anyone can help out here, it'd be greatly appreciated...

Need help asap. I have tried to uninstall this hack, but it does not uninstall correctly. When I try to change a usergroup's permissions, the area for setting the permissions of this hack, still exists (it is just all blank). And when I try to save any setting for any usergroup, I get this error:
