Hi Stu,
I am having the same issue however mine is on Windows 8.1 both x86 and x64. Did you ever manage to hear from them? I sent a few emails, gave up and ordered a GentLED.
Cheers,
Mike
So a quick question,
after replacing the 550 arms, what is the best distance to position the arms as, and you may need to correct my understanding, that the carbon arms need to be trimed?
cheers
