Nikon F3 w/MD4 motor drive...Not working!

Question

Hi...I just won (at a local auction) a well cared for Nikon F3 w/ Md4 motor drive...I just replaced all the batteries...camera and drive ( and yes they are in correctly).. When I turn the power switch on, I get a reading of...m 80; but I can't advance the film manually or with the drive? Any help would be greatly appreciated...Tony PS... I also can't get the shutter to trip...
