With hohner's issue, I'd think it had something to do with your hardware rather than the OS on that particular machine. Try reinstalling WinME, and installing MoH with a 'for sure' working copy. If the problem still persists, get a program like
SiSandra and find out exactly which mobo you got (if you don't know already) Then, look for some online documentation that may help.
vjandme.. maybe you should try a different crack? I think I'm using Deviance 1.11.. and I play MP pretty often.
