I'm having a problem with the game: The Movies

When I first got it (before leopard came out), it worked fine, and I was able to play it with no problem. After a few months, I had a problem with my hard drive, and had to get it replaced. Now whenever I try to install it, right at the end of installation, it claims that it cannot find the proper folder to install it into. Can anybody help me out? Assistance is much appreciated.

Actually, it says it can't create the folder, because I don't have access or something, even though I'm the admin of my computer...
