Actually I did. But apparently I triggered something when I attempted to reload the program after a current CTD. I inadvertently chose the wrong option when I reloaded the sim. Realizing this, I immediately closed it down before it had fully loaded. I restarted my PC and attempted to reload the sim, but this time a screen to calibrate my control devices appeared. When I selected the “next” option, I was presented with the “mandatory update” screen requiring me to complete a 22 Gig upload and install. Took an hour to complete followed by another 35 min to again remove the Xbox entries and the other unwanted content .
