The recorded file comes up as a text document on my computer instead of a recording?  Do I need to download some sort of program on my computer?

The voice recorder is in read only status - you will need to format the device to remove the lock (read only). Go to menu - to submenu and then run the format option. make sure all files have been downloaded as once device is formatted all files will be permanently deleted

the only thing left to try is to try and format the device and see if you can restore it back to factory default settings. You go to the menu and to the format option. This will permanently remove any recordings you have done and as I said restore the device back to factory settings. If that doesn't work then you will probably need to send it to Olympus for repair service.
