Hello! Using an RCA 1080B mp3 player. Windows XP. When copying songs from Windows Media Player to the 1 gig Sandisk (using a remote reader/writer) SOME songs copy just fine. Yet a few will get message "An Error Occurred" & won't copy. I have Acoustica wave converter software & converted the errorred files to mp3 (even though some were already mp3), deleted them from my playlist & re-listed. Still errored out when try to copy to player. Any assistance is GREATLY appreciated!! THANK YOU!! :-)
