Well if you put the software from the MMCD in with the card in a open slot it should work fine. The only time I had a problem was when I tried to install the software first and booted with no card installed. The MMCD is a requirment and you MUST have a legal version of it with the included mach chips installed in your mediator. Sounds to me you dont have them or you tried to install the software from a MMCD update before the MMCD was installed first.
