Audition randomly stopping recording after upgrage to Rode NTI and Scarlett 2i2

So, I upgraded my mic and preamp to the Rode NT1 and the Scarlett 2i2 over the weekend. Now Audition just randomly stops recording with no warning. It's then impossible to restart it and I have to reboot it. Happening every time now. Any idea. Otherwise I guess I'll have to go back to Audacity and I'd really rather not...
