Hey man, thanks!
Good to know you can still play online.
I'm online now.
My mistake was I replaced the d3d9.dll with my own generated by SweetFX.
But that brings me to my next problem. The reason I wanted to use SweetFX is because the game for some reason is way too dark. I thought it was just a bad case of ENB abuse but I remember having this issue as wel with the vanilla game but not this worse. The problem is that the shadows are way too dark or just too much contrast, I don't know. I haven't checked the FX boxes in the launcher by the way, I also haven't checked HDR in the video options. Setting the brightness higher works in fullscreen mode but not in windowed mode, but even turned high things still look off.
I know with SweetFX I can largely mend this issue, as I had similar problems in Just Cause 2, but this mod doesn't allow me to use it.
