Stuck in TWRP!

A

AC Question

I updated SuperSu to the latest version using twrp but now I can't get out of twrp. After updating, I pressed 'reboot'. Then my screen froze. I used the button combination home, power and volume down to reboot but it keeps rebooting twrp. This circle keeps going around. I am desperate for a solution! I can't find anything that comes close to this problem on the web. Please help me
