I just fired up my new build. At first I didn't even install Mystic Light because my plan was to avoid it from the get go on my new build. Setting up SignalRGB went fine mostly just some weird hitches and I ended up installing Mystic Light despite my plans to check something. Uninstalled it afterwards but now the RGB on my Arctic Liquid Freezer III Pro can't be controlled anymore by SignalRGB but it lights up so the header is fine.
Someone has any ideas how to fix it?
