.mac free Jam Pack world music loops

I don't use Garageband much & I'm a little confused about downloading the free .Mac Jam Pack World Music sampler loops. The instructions are to simply drag the folder to the loops browser, which I did. They seemed to download, but I can't find them in the loop browser. In the pull down menu where you select the loops you want to view, if I select Jam Pack World Music sampler, there are no loops in the browser. I tried downloading them again & I get a message that says there's already a folder by that name there. So how do I view the new loops?
