first the "win32 dll" something might came from the upgrade tool itself..my advise is download here an MP3 utlity version 4.05..these will work fine..then the message that says "cannot read or write..." means the firmware is not an actual FULL version..if the firmware is a full version then it will continue to upgrade..

well try to install the tool i recommended then try to recover it with your said full firmware and if "cant read or write.." shows again you need a real FULL firmware.. tell me what happens next..
