I'm guessing this means the dongle is crap...would you agree?
Why do they get corrupted?...was just in the machine that was on a live floor for about 2 years.
Never pulled it out of the USB port.
Machine has been maintained periodically, fans are good, temperature is good.
I throw in a known good USB D75F key dongle with existing GAME & OS cards, and it passed all checks.
Game is back up andd running.
Proved the other key that was in it, is no good.
As far I know....unrepairable?
