Never ending loading

[gulchynsky]

After the last update, a problem that used to occur very frequently, though less frequently recently, has returned. After selecting a livery and airport, I can't load the plane in the selected scenery, and the loading wheel spins endlessly. After selecting a different plane, the problem disappears. I've read various strange methods online to "work around" this, but none of them actually work. Is the source of the problem known, and is there a proven solution?

its common after installing a new livery/scenery of even the latest update for it to take a while to load. find it to be the case the first time i load a flight. it loads faster there after.
