Note: All of the steps under the main troubleshooting thread were taken.
A few months ago (maybe about 4) Reshade was my go to modification to make the game look better. I have reinstalled the game today along with Reshade 3.0.8, and the game simply doesn't launch. I have tried all of the older 3.0 versions. The game icon will appear in the taskbar for just about a second, then disappear. I must also say I have done some minor "troubleshooting" by excluding some files one at a time. The culprit seems to be d3d9.dll. Thanks in advance for users who try to help.
