did you use mbuilder?
if not you can download it here
http://www.dafront.com/~nemesis/downloads/MBuilder.zip
this converts the .map file to map files that mohaa can identify
here are the instructions how to properly configure mbuilder:
Make sure you have MBuilder pointing to the right paths. These paths are all the Default paths:
1) the Game Source directory is pointing to “C:\Program Files\EA GAMES\MOHAA”
2) The compile source is pointing to “C:\Program Files\MOHAATools”
3) And the map source is pointing to “C:\Program Files\EA GAMES\MOHAA\main\maps\dm”
4) Make sure you are saving your maps in “C:\Program Files\EA GAMES\MOHAA\main\maps\dm” and if you do not have the maps\dm folders make them
5) Make sure in MBuilder you do not have anything in the boxes for vis bsp and light on the left!
6) In MBuilder, make sure in other options you do not have Pause selected for all three- vis light and bsp!
