Anyone using Lightspace CMS & LUT Buddy?

I'm getting a Lightspace CMS system for display profiling and calibration/display-LUT generation (I'm going to use the calibration LUT as a Display LUT in Resolve), and was wondering if anyone has successfully used the "LUT Buddy" plugin from Red Giant to load in 3D calibration LUTs from Lightspace?

Until Blackmagic fixes their inaccurate & broken HDLink Pro product, I don't have an outboard LUT box that can globally calibrate the signal out of my Decklink card. So while the Lightspace LUT will work as a calibration/display-LUT out of Resolve, it doesn't do me any good for FCP/Premiere Pro/AE playback, which I need to play back my Resolve grades for final online conform. I was hoping LUT Buddy would work for this purpose (obviously for playback purposes only...I'd disable it for file & tape output).

I can import 3D .cube LUTs created in Davinci into AE CS6 using it's Apply LUT function, but cannot import that same .cube LUT into anything support by LUT Buddy. It doesn't recognize any of the LUT's exported from Resolve 9.
