.Map :: MoHAA Mapping

Hi, im trying to make a singleplayer map for mohaa, so when i want to add an German AI Character into my map i get a this error message

"Radiant MFC Application has encountered a problem and needs to close. We are sorry for the inconvenience."

Every time i try to add a AI into the map (whether it be german or american) Radiant crashes for me. I am aloud to add a Info_Player_Start into my map tho, and radiant doesn't crash.

Please if anyone knows how to fix this error please repost back to me.
thankyou for your time.

P.S. - When i start up my map i get no sound why is this .... i fire my gun but no sound .... please help me if you know how to fix this also.

scrach that

Try using test before the name for the sound prob, test_map.bsp
