Player/Weapon Errors

Alrighty, when I see myself using cameras, my player model (whatever it is at the time) is in the ragdoll/reference position, much like the 1st gmod. In additon to that, some weapons aren’t showing up. For instance, both the pistol and .357 dont show up onscreen, and the .357 doesnt even shoot. Model wont sit down in vehicles either…just the same ref position. Any ideas?
