I have read and read everything about SD exporting to SD card. Whenever I open Jukebox, conect USB card reader/writer, hit on PC buton and then Checkout, I get a window that say "different file system,open settings and format SD. This,I have done repeatedly. Total frustration. I have all the songs from MY MUSIC MP3's converted and stored in the LIST section of Jukebox. Why do I receive that "different file system" message?
