Hi everyone, I'm new in this forum so excuse me if I broke any rule I didn't understand when I read them or sort... ok here I go.

I bought iLife (don't know which version) a year ago or so, and installed it, everything worked fine

But some months ago I erased all my Mac's data and re-installed the whole system again, this time being Leopard

Since then, I can't get to use many applications as well as I did before, but the one that it's bugging me right now is GarageBand

I remember that when I first opened it , it said something about an "instrument library" thing. I can't really know because that message stopped appearing. Now it just won't play any instruments. No, there IS NO instruments, and that's it, I don't know where did they go or what to do

Should I install it again? please help me
