FSX Crashes while loading

Hello, I run Windows 7 64-bit mode. I have not installed anything into FSX recently so I do not know what is causing this. Every time I try to load FSX, I get this error: fsx.exe 10.0.61637.0 46fadb14 terrain.dll 10.0.61637.0 46fadb59 c0000005 0003cdcb 12d4 01ca9cc79b0e71a6 C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\fsx.exe C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\terrain.dll da10351a-08bb-11df-a7cc-00183909cb59 This is my computer specs: 2.60GHz E5300, Nvidia GeFroce 9600GSO, 4GB DDR2 RAM, Windows 7 64-bit.Any help is appreciated :)
