Very Stange Problem (FIXED: VISTA Related)

Ok, I've installed SH4 before with no problems and it was running just fine. My hard drive died and I had to re-install everything. After the re-install everything works fine with the exception of SH4.

I installed SH4 and started the game (without patches version 1.0). When the game started after the intro poems, I only see half a screen (the upper half) and the display is F'd up. The bottom half of my screen is black.

I installed the 1.3 update but now have only a black screen and see nothing. I have to start the task manager and end the (SH4 not responding) process. I have messed around with my video settings and program settings to no end with no results.

I've successfully installed and played SH4 before on my PC, but not after I had to rebuild everything due to a hardware failure.

Please help!

Particulars:
Intel 3,4 Ghz Xeon
3GB DDR2 RAM
NVidia 6800GTS (163.75 ForceWare)
Vista Ultimate (w/all patches)

Advice is most appreciated!
