digidesign midi i/o

Good evening everyone I am running Pro Tools 8 HD 1 with a 96 i/o Power mac G5 OS X 10.5.8. My problem is I am trying to sync my MPC 4000 with the 96 i/o interface, I have an digidesign midi i/o but when I tried to install the OMS from the disc and I get an error saying "you can't open the application "Install OMS 2.3.8" because the Classic environment is no longer supported". Can anyone tell me is there a way around this or what do I need to do. I am trying to use the instruments in the plug-in Xpand. I will not be able to get any midi signals until I get this resolved, I need help!







best regards
