Hi Darius,
That was the problem and I'm amazed at the quick response.
I just have one nagging question. What the sour pickles were ya'll thinking. I can't believe 5 worked just fine with this device and now 6 crashes because of a missing serial number. And I've wasted most of a day trying to get 6 installed. I've never heard of any software crashing because of an USB device missing a serial number and I've been playing with computers for over 40 years. I am totally unamazed that this managed to get out in the real world and waste so much of your customers time, since I'm apparently not the only person that the license fix didn't help.
Cheers indeed,
Larry
