When I opened MSFS it said, I was not up to date. To "update" button pulled up a screen that said, "Microsoft was updated 10.0 to 10.0. Then it said, Flight simulator was not updated, 0.0B to 0.0B. Sounds like, to me, nothing to nothing. Froze up and would not allow me to enter. However, when I start as administrator, all is ok. Kind of crazy. Oh well, it works... so far.
