ALPHASIM F-22A in FSX

Hey all,
Considered the payware forum, but since this is directly related to FSX, decided to post here.
Having upgraded my video card two months ago, I decided to get FSX recently. It still runs fairly slow, but for the most part it is playable, and I'm pretty impressed graphics wise (It looks on par or prettier than my FS2004 install, which is quite heavily modified).
I tried moving the files for my FS2004 ALPHA F-22A, and, surprisingly, everything seems to run smoothly, and all the gauges and the VC seems to operate normally. However, whenever I fly the F-22, the bottom fifth of my screen is always completely black, with the image showing on the top 4/5th. If in VC, the bottom fifth is simply cut off, but if in spot, it seems like the entire frame is compressed into the top 4/5th.
I know its a long shot, but does anyone know what the problem is, maybe a gauge, or something else? I will attach a screen shot soon.
