Connor, have you edited your server's gmod/data/ULib/users.txt? (NOT gmod/settings/users.txt, I can see it seems you did that file correctly)
Or if not edited, you didn't copy the settings/users.txt to gmod/data/ULib/, did you?
If you did, delete data/ULib/users.txt and then join your server and use server console to add yourself to superadmin again.
Megiddo, as you can tell, ULib.ucl.authed is scrambled.
I'm not sure why. He uses special characters in his name in settings/users.txt, does our parser clean that up correctly?
