I have exactly the same problem, and don't understand how the System Information can change just by closing and opening the program! The selected music file cannot be played back because the system information has changed. Click OK to automatically close CONNECT Player and open the CONNECT Player System Information Restore tool. I've lost hours of sleep over this, so if anyone has any ideas... Just to mention, I managed to get the program loading up through the tinyhttp option, but I get the message: The Portable device NW-A1000 failed to initialized and can not be used. Error code: 82040301 I get the same message when connecting it through Sonicstage, even after full initialization of the device.. It seems to work ok through XP, but it's really annoying me that I can't get either program to recognize my A1000 that I bought only a couple of days ago!! This is my first post, so thanks for everything in advance - it's really the best forum out there related to ATRAC/Sony Music stuff~~
