tttbrian, As I suspected the ATJ2091 is one of the newer chips and uses the 9.0.XX series firmware. Because there are no tools yet to backup these firmware versions there are very few available for download which makes it near on impossible to recover a player once it crashes.
You will find the few we have on site here.
