You can download the updates from the open-e website once you've logged in and registered your module.

The serial number should be stamped on the module if you can't boot into the software to locate it. Try registering it but I'm no sure what the procedure is if it has already been registered by someone else.

If you don't have the login details I suggest you email support directly and I'm sure they'll be able to sort you out.

The update is pretty straight forward, download .ISO, burn CD, boot CD, prompt for upgrade or clean install, reboot to USB.

Good luck
