Michael, I only had scenery problems with the manual upgrade from FS9 sceneries to FSX.......Total chaos.....:rolleyes::eek:
Try FS Nordic net for sceneries in Denmark, Norway, Sweden and Finland! https://files.fsnordic.net/sceneries
Don't you think you'll be better off with the FSX Gold-Edition? All FSX troubles I had (Looooooooots of troubles:mad:) were gone the moment I fired up FSX-Gold. All my old props showed up very well, including some 2002 planes I still have. FPS are great......

Did you try "Finland-X" for FSX? Edit: all lakes are frozen in winter (and landable) even the sea is partial frozen, great improvement with ground-textures
