Pen Pressure Still not responding in Ai

I have an Wacom Bamboo CTH460 and I recently ran into a problem with my Pen Pressure in Ai. I'm Running Win 10. and have all the current updates/drivers for my equipment. I have followed pen pressure tutorials for calligraphy brush adjustments with no positive results. I keep getting a stroke with no weight differences with different pen pressure on the hardware end. I have also keep resetting wacom and Ai preferences, this also seems not to help. Pen pressure works in Photoshop CC though. Any help would be awesome.
