Thank you, Everyone. I have 5 upgrades left. Even if I didn't know, when you go in to Jaws and press control insert v, it tells you a good deal of information. It gives the serial number, first 7 digits of the authorization number and the locking code and the number of upgrades. So, I certainly knew that information. What I didn't know was the procedure regarding upgrades and whether they had to be ordered or were sent automatically. Thank you to all who understood and answered my question. And, the representative I dealt with who sold me the SMA was Keith Patterson. Katherine
