I just purchased GB10 last week and I repeatedly keep getting the following message, "Garageband was not able to install the new sounds. Close and re-open Garageband to download and install them again." I have tried EVERY suggestion!

I just purchased GarageBand 10.0.3 last week and I repeatedly keep getting the following message when I try to download ANY of the FREE Piano lessons in the "Lesson Store", "Garageband was not able to install the new sounds. Close and re-open Garageband to download and install them again." I have tried EVERY suggestion that I have come across on the internet and nothing is working! If I'd known I would encounter this issue, I would not have paid for this. Tried restarting, rebooting, reinstalling, deleting the cache, and on the verge of just reinstalling the OS. I have come across people have the same issue for months and I can't believe Apple has not offered a fix or update or anything.
