MSFS flight plans take an excessive amount of time to load after World Update 11

[Jimrh1993]

I had weird problems like that awhile back and what I ultimately did was to totally uninstall everything, track down any and every file it installed.

I removed all traces of everything MSFS related and slowly installed one part at a time checking after every part.

Eventually everything was reinstalled and it worked fine.

I hesitate to suggest that because a full reinstall takes days.

One more thing:
There’s a HUGE update in the pipe and chances are that everyone and their brother’s sister-in-law is downloading it.

Maybe that causes problems?

The 40th Anniversary Edition is a milestone to the dedication and love that Asobo have put into the game, I wanted to say thank you!

'Twas the night before the update, when all through the sky Not a plane was flying, as the moon hung so high, The forum dwellers waited patiently, waiting without despair, In hopes that 40th Anniversary Edition soon would be there; We are almost here guys, a massive milestone for Microsoft Flight Simulator, its been a wild ride so far, we’ve had our ups and downs and problems and successes, but I want to thank all the team at Asobo who have worked so hard to give us free and regular update…

One thing you can try is to enable “off-line” mode for the game. That way if the network or servers get hammered, you can still play, just w/o the streaming scenery.
