Won't work with Leopard?

I have a registered version of Podworks that worked well on my last Mac. However, on my new MacBook Pro, it doesn't work. The most I could get it to do was load my files from my IPod into a folder called "former ITunes libraries" but there was no way to transfer from that folder into ITunes. I then got an "error message" that said some of my files did not transfer correctly, and I hit the button that said to try again. I know Podworks works well once you can get it to work. But the lack of clear documentation anywhere (in terms of "first do this, then do that") makes it very clumsy to use.
