I had this problem with a corrupt pk3 file created by another user...so if you're using any user created skinz, maps, etc, try reinstalling mohaa (including registry cleaning in between uninstall and install) and firing it up just with the stock skins and see if that works. If it does, keep adding user created files one by one until it crashes, then you will have identified the corrupt file. You can delete that file then add all the others and you should be ok!
