Hi Shock,
My fault, the file doesn't exist anymore.
There's two other firmware files available which are similar:
http://www.mympxplayer.com/dload.php...ile&file_id=56
http://www.mympxplayer.com/dload.php...ile&file_id=19
Hope that helps.
Please also be aware to NOT upgrade your firmware unless you have a good reason and a good backup of it. Updating the firmware of your player with an incorrect version can give you a 'dead player' so be very careful.
