OKAY RAT HERE YOU GO. I AM JUMPING AROUND FROM THREAD TO THREAD BUT I THOUGHT YOU WERE MORE LIKELY TO READ THIS ONE.
I did as Druid said and I had some problems but eventually it worked.
Here are some helpful hints:
1. You have to type exec custom.cfg everytime you start MOHAA.
2. When I first did that everytime I would get on the server my computer would crash hard. Real hard.
3. When I didn't type exec custom.cfg each time I would get booted off and the game was super slow.
4. I finally deleted all of the other cfg programs out of the main folder: autoexec.cfg and unamedsoldier.cfg. When I deleted those everything worked great. It would lag a little but not bad.
5. You will have to reset all of your options if you delete those files.
Good Luck
>>>>>>>UPDATE<<<<<<<<<
I SPOKE TOO SOON!
Okay, I take it all back.... I did all that and it still kicked me! I give up!

CAN ANYONE HELP?????
RAT IS IT WORKING FOR YOU???
