I am currently running Snow Leopard on a MAC OS 10.6.7 I didn't have Snow Leopard when Logic was originally installed. My hard drive was recently replaced. While re-installing Logic 8, when I started with the Jam Pack 1 DVD, I got a message saying there was an error and I'd have to try reinstalling Logic again. However, when I checked my applications, Logic was there. I opened it and most of my songs looked and played as they should. I then discovered that the Apple loop and the Indian Bansuri flute I used in one song are nowhere to be found. Neither plays properly. Weirdly enough, the loop used for the bridge plays fine...but I didn't see it in the loops bin either. While searching for them, I realized some loops and instruments are missing. Another I couldn't find was the Russian Balaika bass (used in a couple of other songs). So my questions are: ~Could this be because the Jam Pack discs didn't load? ~What is actually on the Jam Pack DVD's? Is there a way to tell what I'm missing? ~Will I have to re-install Logic yet again and hope the Jam Packs install this time? They won't install otherwise. I found the Russian Balaika, shown as a music note icon in my documents folder but how do I get it to load back into Logic?
