Hello there! I'm bought my Eris a week ago and am not familiar with all of its functions. I'm trying to place my music files on the SD card. Whenever I plug it into my computer and mount it shows a USB drive under "Computer", but whenever I click it I get a popup saying that the drive can't be found. I've downloaded HTC Sync and that let me create a music file, but then I couldn't do anything with it. Is there something I'm missing? Thanks for your time!
