Hi! So 4 me was the same problem, but after I fixed it it was fun. OK, first open your Start Menu , then select RUN , type 'msconfig' u will see a couple of solutions there. U must choose 'Diagnostic Startup' "load basic devices and services only" . Accept this, then restart ur comp, then start mm8 it will work properly, but no sound. No problem do 'msconfig' again then put back ur previous startup. MM8 will work now with sound. Dunno why need to do this, but 4 me it worked. Have fun !
