Not starting up

I gave Gmod to my mate and hes got all the right files and all that crap but the shortcut keeps screwin up

can anyone help?

Pirated?
If so, that’s your problem.

but it works perfectly fine on my computer

and if the short cut does work it comes up with " cant read file Backround01.vtf" even though he has it

If it’s pirated, we can’t help you. Go buy the game you cheap fuck.

oh thanks mr. polite

say, could anyone email me the instructions on how to build your own map?

just go on fpsbanana and look at the hammer tutorials (or you know google it… xD)
