Hi Otiasj. If you've got a spare minute at some point I need your help. I finally took the plunge to use the ml_sony plugin after getting thoroughly annoyed with Sonicstage. Created a fresh database. I have a model NW E405 which i wasn't sure was protected or not so installed GYM anyway and I think I have the datakeys properly in a GYM folder in the C drive. Fired up Winamp and everything seemed to be working perfectly. I could send tracks to the player, remove them again, through Winamp play the tracks I'd added. I unplugged the player and could see the track details of the first track. But when I tried to play that or any of the tracks all I saw on the display was a cross with "MG Error" and the tracks won't play. Any ideas what the problem is or how i can fix it. Thanks a lot in advance.
