I downloaded the premium library and saved to 16 GB SD card, getting “invalid SD” message. Sandisc Extreme. Do I need to unzip the folder before inserting into BB? The card was already formatted and other data is on it. Please advise.

@persist You are a hero! Thank you!!! Your instructions are so clear, they should be what everyone uses. I can see where I went wrong in a few ways. I’m going to be saving this post for future reference for other packs, etc.
