Ok lets start off at the beginning.
1: You may have already done this but copy all maps before you mod them.
2: Once you mod a map, then you have to host a server on that map, otherwise you will just get an exception.
3: If this continues then im afraid the only solution is to reinstall Halo.
Hope this helped.
