Running ableton in rewite into Cubas-says I'm not authorised

[mbira]

I'm trying to open a Live set within Cubase 5 running Ableton as rewire. When I open Ableton, it tells me that some features of Live have been disabled and I can't save. Why is that? I'm trying to figure out how to easily move loops from within live to cubase for mixing and editing.

I should say I'm running Snow Leopard and Ableton 8.0 and Cubase 5.5. Also I have Reason open in rewire in Cubase, and Reason is usually used in rewire feeding Ableton in this set-not sure if that would matter.
