ULX missing folder

[chester]

You can either follow the standard GM10 way of adding users
(http://wiki.garrysmod.com/?title=Player_Groups), or you can add yourself directly to the
data/ULib/users.txt file. DO NOT EDIT THE ULIB FILE UNLESS YOU KNOW WHAT YOU'RE DOING.

Ok, not being mean here..just honest, and that may seem brutal.
Since you have to ask...that means you don't know what you are doing, and should therefore read http://wiki.garrysmod.com/?title=Player_Groups
That document explains a totally different file, made by/for GMod itself, and most other scripts, including ULX, will read it to determine superadmin.
Read it, follow it. Avoid editing the ULib/ulx files for a long time of learning curve.
