I just opened up DCS to do the F-15C campaign, but upon entering, I realized my key binds weren't working. I opened up controls expecting me to have set something wrong, only to see that all my controls were gone and that about 80% of the controls were greyed out, without any option to add new controls. The only controls that I could add were view controls and function key controls. I scoured the internet but couldn't find much on the topic. I deleted any custom content I downloaded, such as a mission, and the clickable FC3 mod that I wasn't using. I deleted all the input files from the saved games folder, and also from the main folder, in the Mods/aircraft/Flaming Cliffs/Input. I also went and updated the drivers for my HOTAS. The HOTAS I have is the Winwing Orion 2 throttle, with the F-15EX II grips, and the F-16 EX joystick. Nothing that I have done has helped at all. I was even playing the F-15C earlier that day and everything was fine. Any help would be appreciated!
