So, I'm specifically trying to import the Roland TR-808 Kit from the Garageband Jam Pack: Remix Tools. But this applies to all of the Garageband instruments. I click import (not the down arrow, but the actual 'import' button), and dig through all my files until I reach the file (HD > Library > Application Support > Garageband > Instrument Library > Plug-In Settings > Drum Kits). Click open, and nothing happens. The menu doesn't drop down so I can drag over the sounds, and if it does, I drag them over and they are just silent. No sound. What do I do? I need help or I might throw my computer. Thank you.
