Once I unzipped the files, I opened Jempeg and selected "Upgrade Empeg". I tried three files, to be "Upgrade" - emptris
BZZZZT, that's the problem. You've hosed the player probably.
The only file that can be an upgrade file is one with the file extension of ".upgrade" and instructions on their use can be found
here.
Please get the appropriate upgrade file (in your case probably car2 developer) and do this:
- Unplug the power from the player.
- Start the upgrade by double clicking on it.
- When it prompts you to apply the power, do so.
