I added a playlist called "Singles". There are about 650 files in this playlist and every time I tried to drag and drop it, emplode would lock up. So I created an empty folder with the same name and added it. Then I tried to drag and drop the files in smaller blocks. First I tried about a 100 at a time, but it still froze up, then I tried 10-15 at a time, and it worked the first 4 times I dragged items over it (without syncing) but the fifth batch caused it to lock up again. I'm running version 1.03. Any ideas?

One of the files in that fifth batch might have a corrupt ID3 header - try each of the files in that fifth batch one at a time.

Hmm...I'll give that a try. FWIW, I did retag all those files with MP3Tag-Studio before I tried to transfer them. Thanks for the tip.
