Another way to fix this:

When you press the RESET button on the back, hold down the scroll wheel for a while. This will activate a special setup menu. Make sure your network settings are correct, then go to RESTORE -> MARK FOR UPDATE.

When you reboot it'll check the firmware on the remote. If it's old it'll upgrade it and you'll be fine. If it's already the most current, it will still ask if you'd like to force an upgrade. Do that and it should (eventually) reboot fine. Note that you'll lose most settings (including the ICF file).
