Garry's mod not finding internet games?

I just re-installed Garry’s Mod after reformating my computer, and I’m getting a problem with finding games from the internet tab.

I don’t have a problem finding them from history or friends. (Haven’t tried favorites yet)

I checked my firewall, it’s ok
I checked my connection, it’s fine

What is my problem? =S

Update… i think. someone said that there used to be a virus so garry had to fix it… only problem… i dont know how to update it
