Dave, I can't tell you exactly, except that, having explained in detail to George, he contacted Avid. What was said in that phone call, I don't know, but its upshot was that Avid provided him, who then provided me, with the required serial number and registration details, which I duly entered. I hope that helps a bit. Roger If you wish to unsubscribe, send a blank message with the single word, unsubscribe - in the Subject line to: sib-access-request@xxxxxxxxxxxxx
