Okay, so it's not an MP3 file.

At this point, do the following:

- Deinstall Rio Music Manager, Rio Taxi, and Rio Internet Update using the add/remove programs feature in the Control Panel.

- Delete the Program Files\Rio folder from the hard disk.

- Clean out all of your temporary folders completely and clear your web browser cache.

- Use Ad-Aware and a virus scanner to make sure you have no spyware or viruses.

- Download the latest version of Rio Music Manager from the rioaudio.com web site and install it. See if it works.
