In order to free space on my iBook I decided to move all my songs of my two albums to a hard drive. To make sure none of the loops and samples are lost I need to save the songs as "Archive". This worked fine for most of the songs, but for some this option is disabled (grayed out). I've tried to restart my computer, resave the files and so on, but nothing seems to do the trick. I'm pretty frustrated at this point. BTW - I was not able to find a solution on the Apple website either. Anyone knows how to solve this problem?
