To me, fadmin and darkrp are synonymous.
So, no, DarkRP doesn't work fine with ULX by default.
Stingwraith, you answered your own question in your first post, if you're going to ignore our attempts to help, so be it.
You installed some stuff recently. Things started acting up.
Seems to me, beside having an older version of DarkRP we've seen repeatedly have issues with ULX groups, some mod you've installed has added more corruption.
