Earl, just select any style category, then tab across to User, which will reveal the styles I loaded in the onboard user memory, the next tab position should be the SM card, which holds a huge number of style files as well as registrations, and the final tab position should be the USB drive. If the USB drive does not appear, then the drive is dead. If this is the case, merely purchase a new USB drive from Best Buy, or wherever you can find one, copy my backup USB drive files to the new drive, remove it properly from the PC using the safe removal procedure, then insert it into the keyboard and it should show up with all the files you need.
If you need to call me, I will be here all night tonight,
Gary
