When I load the game, and attempt to play HTF or the new DM maps, textures aren't loading. So instead of see through nets and fences I see a big block of white. This is a major problem, and I do have every texture and file. Any tips?

Press Alt+Tab and that will fix your problem temporarily, while we find out how to fix this.

Rebooting fixed it ^_^

I also had some trouble with the new Maps. I think it was...Htf_Void that I was trying to play on. I'd join the server, stay on for about a second and a half, then it would boot me off saying "Wrong Map Version Detected", so then I'd rejoin and it would download the map, get to about 4%, then I'd be back in the server. Then I'd get kicked off again. I kept trying for about ten times and then I gave up.
