Revolution Slider on Internet explorer

Hi having issues with revolution slider in particular internet explorer v11 (not sure if other versions yet) – seems fine on edge. It seems to be failing to load. There doesnt appear to be any errors in the console, but since the slider fails to load, it then doesn’t load any other images on the page. Is this a known issue? If so is there a fix or is it possible to fall back on IE in someway even?
