Help please?

I have blocked out a pretty basic, small, one CP-map. It's not done yet, I just started on it and spent 2-3 hours on it so far. Everything seems to run fine, but after I added the team_control_point_master entity the CP was locked and if you touch the triggerarea the game will crash.

Why does it do this? Help will be much appreciated.

I think so. I can't check in two weeks or something like that, as I'm going to be in Denmark. -.-
