REFERENCE APPLE SOUNDTRACK DOWNLOADED AT LIMEWIRE.

System G5 Panther.

Hi Guys,
I wonder if anyone out there knows anything about this.

I downloaded and installed the APPLE Soundtracks application.Got serial number,put it in.Great. It worked.

I had to then erase my harddrive and reinstall panther and soundtracks.

Since I have done that I get the error "can not licence 4xxx" when I try to re-enter the code. It's almost as if the mac knows I've had this program installed before and won't let me install again. Any advice would be greatly received.
Many thanks.
