My sandbox has just started acting up! First, it would slow down a lot when I was near water, so I turned off some water shaders. Then it stopped loading certain maps. I tried a lot of other things, but it wouldn't help at all, so I tried to reinstall the entire program. (I'm using a mac, and I don't think there's an official way to uninstall/reinstall.) When I reinstall everything again, I still have the same problems, only this time, I have only one playermodel, which is an un-animated rc. Is there something I can do to set everything back to normal. I'm really upset

because I love using sandbox, and the map I've been working on for months is one of the ones that won't load. Thanks, I think this forum is awesome!
