MCC NOT LOADING AT ALL,

iVE LOADED MCC ONTO MY SEPERATE HARD DRIVE and HAVE ONLY BEEN ABLE TO LOAD MCC ONCE AFTER FIDDLING WITH MANY SETTINGS. SINCE THEN, IT JUST WONT LOAD. i SUSPECT THAT IT COULD BE THAT MCC IS LOADED ON MY SEOERATE DRIVE D: AND NOT ON THE OPERATING SYSTEM DRIVE C:.
Please advise, it would be greatly appreciated.
