So, I updated my Script Dragon files to supposedly be compatibile with the latest patch, but the dinput8.dll that it updated seems to make Skyrim think that I'm using an unsupported version of the game. Removing this dll fixes the problem and allows me to play as normal, but obviously my mods that require Script Dragon don't work as intended. Would simply getting an older version of Script Dragon's dll fix this problem, or do I need to wait for Alexander to make a new one? Any help would be greatly appreciated, especially because I can't really play my modded game with this problem. Thanks!
