Well, It just says that i should put some lights onmy map, but i think it's not the cause, is it?

I made some doors with the same textures of the walls to make some kind of "secret passage". I'm sure there are no "holes" (is it leaks?) on my map....

superjer help here plzzzzzzzzzzzzzzzzzzzzzzz!!!

Hi, I used to run my map normally but, after some changes (doors), when i put NEW GAME and select my map, it loads untill the half and shuts the CS down?? Why is that??
