If you're having the same symptoms, including the map image never showing on the connection screen, then you might not have the same root cause (Windows 10 "controlled folder access" turned on). Something else might be preventing either the FAF client or the game from accessing the maps folder. Perhaps the two (FAF client and game) are looking for the maps in different locations. I would start trying to figure out if there is something going wrong with the map download, generation, or loading by the game.
As an aside, using Windows 7 at this point is pretty scary from a security perspective. I realize even installing the FAF client is also a kind of scary security issue, but using Win7 is next level. If you can update to an OS which gets regular security updates, that would be a good idea. Don't do any banking or such on that Win7 machine!
