Hi, just got the 80HE and i love it. as an ocd freak i deleted all the profiles it comes with and created one of my own (a profile that you can store in the keyboard)
then when i tried to saving it to my keyboard the save button becomes grey with a loading icon indefinatly (gave it even a few mins)
after a bit of a headache i found out that if i have two profiles, each of them saves perfectly (even an inactive profile)
