Hi, after wiping my hard drive I found myself unable to reinstall GarageBand (which I use for my work and cannot live without!) I obtained the iLife 5 install disk and did a full install. After getting an "installation successful" message I tried to open Garageband and I get an error message that says I have an invalid Instrument Library. I do have the library in the place it says I should have it but the app still doesn't open. Maybe I should uninstall and reinstall GarageBand/iLife? But the disk does not have the uninstall option. Please help! thanks to all in advance.
