I've had MFSX for a long while now so I was getting pretty bored of the included aircraft & always wanted a V-22 Osprey for the game. So I took a chance & gave the SimShack version a try but it doesn't seem to show up in aircraft selection after the download & install process. Even tried one of their free addons(the F-16) Any idea what the heck is going on here? I'm trying to use this on a CD installed copy of MFSX on Windows 10. PC hardware is more than good enough to handle flight sims so my PC isn't the problem. Did I get ripped off? Is SimShack just a bunch of con artists here? Keep in mind this is a CD installed copy of MFSX & not the Steam version. I don't want the Steam version & shouldn't be forced to buy a game I already have just to get an addon to work.
