ATEM Control Layer - not working?

I just finished 3 days of production using the Blackmagic Design ATEM Production Studio 4K as our 3 camera HD switcher (It takes rendering load off the production laptop and provides a multi-view preview.) We convert the Studio 4K’s HDMI out to Thunderbolt using a Blackmagic Design UltraStudio Mini Recorder.

In an earlier version of MiMo (beta) the ATEM Controller layer worked fine, but this past weekend (using the production release Version 2.0 (21625)) I was unable to use hot keys inside MiMo to switch the ATEM sources. I was networked to the ATEM and ultimately used Blackmagic’s software to control their box - but that meant jumping out of MiMo to change camera sources.

I re-imported the ATEM control layer to no avail. My ATEM Controller layer is dated Feb 18, 2015. (I bought it in late March and see a file ATEM Controller.qtz dated April in the GroupContainers folder in my user Library folder … and another in my system Library folder – I did not delete these files before re-importing the Layer)

My ATEM hardware is shipping home right now so I can’t do any debug for few days - but I wanted to raise this issue to see if anyone else is having this problem.
