I am having the same problem. I also have a Vaio pocket. Have run the KeyWizard and the GYM program opens and shows the files that are on my device. The vast majority of the files are in ATRAC format and these ones I am unable to play or save them in GYM. I have a couple of music files in MP3 format and I am able to play and save these ones. Do you suggest running the KeyWizard again? Or is there another solution?
