I just bought a new V2 scan and tune, and got it in the mail today
When I pulled out the licence, I was somewhat surprised to see that the Issue date was 01-Jan-2000. I entered the details exactly as on the card, selected "Scan and Tune Commercial" -- Exited out of the program, unplugged the interface, and re-started v7.5 tune tool. Then I get the "Authorization set to DEMO mode" error message.
I am guessing there's an error somewhere??? Seems to be able to open and save tunes fine with the scanner plugged in, but when it's not, I'm restricted to demo mode.
