Hi. I've been searching for a answer to my problem. If this is in the wrong place, mods please move. My problem is that I've been trying to import WMA files from my PC onto a playlist. I did it before, and now ive forgotten. This time nothing seems to be working. A few times ive even had a windows error message. Anyone know whats up? How can I get my WMA file onto my device ? Please help Thanks!
