EP2 Not showing

I have EP2 of Half Life 2. On Gmod, when I spawn EP2 content it gives the Error model. I was wondering if someone has ran into this problem and fixed it cause I really hate seeing errors when Im playing with friends.

Did you launch EP2 at least once? Is the GCF mounted? (check if it’s mounted in the ‘Extensions’ menu)

I checked and Gmod registers Half Life 2: Episode 2 is installed and working. Maybe I’ll do the 1st thing you said. Ill post if it works.

Added: It was the fact I didn’t launch it and updates didn’t get installed.
