Hello, I just downloaded and installed ML_SONY today and I tried adding mp3 files to my NW-HD5. The files add properly in Winamp and I pressed apply and it all went alright but when I disconnect the mp3 player, while it's creating the database it says "mismatch in system files". I was wondering why I get this error and how I would be able to fix this. Thankyou so much in advance.
