Last Friday I downloaded the 4.3 upgrade. When I tried to install the upgrade I was getting the message I did not have a registered/activated copy of the Pro Pack. I new that I did have it and 4.2 was running.  

I had forgot that in early April my boot drive failed therefor all my registry information was gone when I replaced the boot drive.  FSX and all the files were on a separate drive.

I opened a trouble ticket, provided an order number and an explanation.

Within 2 hours Captain Sim provided me the link and the order number. Downloaded the package, installed it with no problems  and was off and flying.

Thank you Captain Sim for the prompt response.
