so i accidently changed the rendering setting to software and now I'm getting a runtime error. I cant even start it up cause it will open this error up. problem is I need it to be direct x again..... how can i return it to default setting or (normal settings) If i cant even start the game to change the settings. I tried deleting and reinstalling it. but it did'nt reset it. what file do i need to delete to return the user settings to normal?
