Mach Five and Cubase SX2

[Ljam58]

I recently installed a new hard drive in my Mac dual processor 1.8 G5...I installed OSX 10.5 and reinstalled Cubase SX2...Everything worked fine til I tried to reinstall Mach 5...I had Ilok key issues(long story)....Now Cubase won't start up ....What I want to know is: How do I fully uninstall Mach 5....DP5 and Logic ignores the Mach 5 issue but Cubase won't and of course, all of my music is on Cubase...Can anyone tell me how to uninstall Mach 5 or how to make Cubase ignore it??? Thanks....Leon
