Logic Pro 9 Jam Packs


I have have Logic Pro 9 which I got when it first came out. I have installed it on 2 different Mac Books. When I got my new one a few months ago and tried to install it, the Jam Pack disks would not install. After contacting tech support it seems like the disks are corrupted, and cannot be installed.
Anyone have any ideas on an alternative way to get the Jam Paks??
