When I press the button in the options tab that is supposed to start VR, gmod just closes out and vr starts up. It's rather strange, though, because it was working just last week and I haven't done anything to change it. I've looked through the discussions and comments and have not found a solution. I've also looked at the description, and the solutions there didn't work either. I get errors during the loading screen labeled "ppp". I'm not sure if those are this mod or something else happening.
