No CS weapons with CS:S mounted?

I own Counter Strike: Source and GMod 10 (neither is pirated, so we have that), and Counter Strike is mounted in GMod. I used to have access to all the Counter Strike weapons (i.e. snipers, pistols, etc) in the weapons menu. A while back, however, they just…disappeared. Any ideas?

You probably had this:

Well for some reason the page at that link has nothing; however, i am in-game at the moment and i suppose a recent update or something has fixed my problem. Thanks for helping anyways.

btw, title should say “No CS:S weapons with CS:S mounted?”
