After about 3 months of use my copy of MSFS 2020 stopped running. The icon on the task bar disappeared. Under AllApps the MSFS was grayed out. I uninstalled it and reinstalled it. The moment the installation was complete it asked for my code. Immediately after I entered it, the program stopped running. I still have the grayed out icon on the task bar but no running program.

I have been using the MSFS 2020 program for around 3 months. Yesterday it stopped working. The program icon disappeared from the task bar. When I clicked on AllApps the program showed up but was grayed out. I had made no changes to my computer since the MSFS had run previously. I uninstalled it and then reinstalled it. It appeared to install correctly. It requested and I then entered the 20 letter code from the card that was in in the box when I bought it. The MSFS 2020 program then immediately stopped working. I can again see the program grayed out in the list of programs. Any help would be welcomed. Ron
