Just my luck....help please.

Now that the ace file problem is fixed, seems that I've encountered a new one. Downloaded the file, replaced the original with the cracked .exe ( Hidden & Dangerous Deluxe English v 1.50 ) and when I try to play it, this message pops up:

The game was installed from CD-ROM drive D:.
This CD-ROM drive cannot be found. Please re-install from valid CD-ROM drive. The game will now exit.

The game runs fine before I apply the crack. I only have one CD-ROM drive on my pc ( Windows ME ) and it is labelled as D:. Any ideas anyone?
