this thread is like 3 years old and i'm sure the issue got resolved because i cannot think of a single case where using a different USB stick wouldn't have solved the issue. unless the Profiler in question has a hardware problem. Saying that, we've offered you to repair broken LEDs on your Profiler years ago and also the hardware for you. I'm not sure what else we could do. From what I can see you've never send your Profiler for repair.
if you need additional assistance, contact support by email.
So the thing is i have to be without my kemper (i use every at least weekend) for a month (in the best case cause i am sending to Germany from Spain) and pay for renting a new amp while you repair it?, and i have to be agree on that? If i buy a car and it has a problem, i am not paying for a renting one for example, or it is just in Spain that we are the most stupid country in the whole world (i think, Europe is enough)
