Don't know what's going on but game crashes everytime I try to start it... I have t4m as well, maybe my computer just sucks

I hope all my replies aren't like this but I cannot play this map.  It won't load, just goes back to the main screen after I launch it.  It's a shame man, like a third of the custom zombie maps out there don't work, at least for me.  Any suggestions again would be ...

Doesn't work for me, after I launch in mods it goes back to the main screen.  Also, tried /map e1m1 at the main screen and nothing.  Anything I'm doing wrong?
