I've spent 2+ hours looking for a solution to this problem. I'm trying to transfer all my music onto 1 atrac CD since I dont want to take 10+ CD's when I go camping. It's all in mp3 format, mostly ripped from CD straight to mp3 using audio grabber. Some is downloaded, and some was ripped from CD to wma then converted to mp3. Absolutely none of it will transfer to the atrac cd, it just gives me the error Transfers are not allowed' for each track. I'm on the latest version, SS4 cp. I tried converting some to wav, they get added fine. This isnt practical as 2 albums came to 700mb, and I want to convert more like 40-50 to atrac cd. Any suggestions? I got until wednesday to sort it out somehow
