Garry's Mod Content Help

I just got Garry’s Mod and I have all the Half-Life 2 games, TF2, and Portal. My friend gift passed me CSS and DoD:S and I heard if someone gift passes something to you you would get the content in Garry’s Mod but I don’t, What’s wrong? Any help would be appreciated.

You need to OWN the game, gift passes do not work.

thanks you finally someone answered my question!!! I love you!!!

:ohdear:

No problem.

I’m sorry but isn’t a gift pass something like they buy it for you and you install it. permanently. if a gift pass is permanently it works(I’ve been gifted hl2 and it mounts perfectly) just correct me if I’m wrong but I think a gift pass is a permanent gift to you. so it should just work.
