I'm having the same issue. I contacted the developer on Nov. 17, 2015:
"Hi Chris,
Any updates on when this glitch in accessing Sabre bookings be resolved.
It doesn't seem to work on the website either.
Thanks"
And reply from him on Nov. 18, 2015:
"Hi - not yet I’m afraid - I just haven’t had a chance to look at what other options there are, I just know that the old way won’t work!"
