Thanks for the reply Phil, quite possible I'm being remarkably stupid, but when I attempt to register the HX FX unit and fill in all the details, the serial number box already has "21hfx" entered. If I submit that I get an error that the serial number cannot be found and registration fails. I'm assuming I do need the serial number of my device, which I'm having trouble finding thanks to no sticker. I've got it connected to HX Edit but can't see any device serial mentioned anywhere. Am I missing something obvious?
I'd like to buy HX Native and obviously want to pay the discounted rate!
