As above.. I have been using SweetFx for years. Had to repair my game files in BF4 and when finished SweetFx no longer works. Ive re-installed SweetFX using the same methods Ive used before and it just wont start. Really confusing. In configurator it says active. When I hit Scroll lock key in game (145) no change. I'm usually really good at this sorta stuff but since I cannot figure this out I ask for help from the SweetFX gods.
