It's starting to look like, with the experience level of discussion here, if you don't know how to use ulx addgroup to put a group back and inherit user, you should just see our FAQ section of the forum for resetting ULX to default/factory reset.
We also have a FAQ for how to disable FAdmin.
And iViscosity - no worries. Team Ulysses ourselves have trouble with integrating/letting ULX work with DarkRP.
We thought there was progress last year with a 'common' admin function library, but, well, yeah, that seemed to go belly up.
