Of course I go on and complain in the Prepar3D forum about the newest release coming out tomorrow. I decide to startup X-Plane and guess what happens, the update screen tells me that v10.4 is ready for download. Of course I immediately downloaded the newer version. Only thing I am seeing so far is that the old situation files are corrupt. This being my first X-Plane upgrade that is something that I didn't know.
Oh and it didn't cost me any additional money. I might be spending more time in X-Plane that P3D now.
