Hi forum

I don't really know if this section of the forum implies for Crysis (2007).
But if so, then I got a little issue

I recently patched Crysis to 1.2.1 but now when I want to change the graphics is crashes and saying Crysis doesn't work anymore ?. Before patching It was all good.

My specs:
CPU: AMD Athlon II X4 640 3.0Ghz
GPU: Sapphire HD6870 1024mb
Ram: 4GB RAM DDR3
OS: Windows 7 Ultimate 64bit

Thanks for helping
