Uh, er, um, actually Megiddo... ULX v.8 through v1 had a ulx_config.lua
*shudder*
I hope for our sake he has the wrong error.
Ion,
If that error is right, uh, well, er, um, Ion... UPGRADE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Heres the run down.
If you have Gmod 9, you will need ULX latest = 2.2, ULib latest = 1.2 (Any versions higher than those won't work for GM9)
If you have Gmod 10, you will need ULX latest = 3.02, ULib latest = 2.02
