Cubase LE 8 recognition problems

Hi! I have installed the Cubase LE AI 8 on my Mac (running El Capitan) and am facing some issues with it. After ensuring the Device setup on the interface is set to Scarlett 2i2 on audio input and outputs (and ensuring the same on my system sound preferences); whenever I try to record a track, I get a message saying that “Recording Error: ASIO driver is not running”. I also get nothing for the headphones. Request please help!!
