Hey Ive had the new version for a while i just told 2 of my buddies about it and when they install it for some reason it doesnt show up in their games list, is there a quick fix for this?
One of them had it work once but reinstalled and cant see it.

They have both reinstalled it quite a few times restarting steam and their comps, so i dunno what the problem is

See this thread.

Make sure you own the required games.

Post in that thread if you need to.
