Clone CD and Alien v's Predator 2 help needed
 

Hi everyone.
I am having a problem backing up Alien v's Predator 2.
I have the retail cd's, and am using CloneCD to copy.
When I try to install the copied cd's, they work ( although rather slow ) but it does not play when I try to run it.
My cd burner, and dvd/cd-rom are both supported by the newest version of CloneCD so I am stumped on this one...
any ideas
thanks
HR
