Issues with rewire

So Reason was working fine in demo mode with Rewire in Cubase 8.
My soundcard works fine with cubase.
It initially works fine with Reason stand alone.
When I go to open Rewire it says my Soundcard is not working.
Before I open Rewire, the Audio section in preferences is fine and there is a green tick next to my soundcard.
After Rewire, the Audio section is just grey with some jumbled letters placed over each other.
Also, when I could get Reason and Cubaseworking (not with Rewire) Reason threw out the programmed drums in cubase, but not the music tracks??

Cubase 8. Win 8. 500gb HD. Cubase audio soundcard.
