Using your XP computer you should be able to update the M1XEP to version 1.3.28 then update the Bootware to 2.0.4 so that you can update the Firmware to the latest. It would also be possible to update to 1.3.28 then run the Special M1XEP Updater Utility and get the M1XEP to version 2.0.38 before updating the Bootware to 2.0.4 and the Firmware to 2.0.48
