Need help reinstalling MSFS

[Partially 8]

Hello and here's my problem.  Due to a series of errors on my Steam version I unfortunately validated the local files on the Steam version, lost the content, uninstalled and reinstalled the Steam MSFS.  I was prompted to update with a 100 Gig download to my the in-game suggested appdata folder chain.  After doing so, I restarted game and was presented with the same update instructions I had received previously.  Can't proceed to the "world" start screen. Has anyone had this issue and solved it.  If so, I'd appreciate the solution.  Thanks

Pete

Yes, i had this problem, when i reinstalled MFS2020. I had to reinstall all the contents in profile.
