PT11.3.1 Not Playing ProRes LT

Has anyone experienced this.

Import a 29DF ProRes LT file onto the timeline. Not trying to play it out a video card, just want to view it on the screen. Hit play on the transport and the video doesn't play. The session does, but not the video. I have the most current ProRes Codecs on the system.

Mac OS 10.9.5
PT OS 11.3.1

HD Native PCIe card installed in a 2.26GHZ 8-Core 32G RAM
UAD Quad Card
Black Magic SDI Card (but not trying to play out of this)

Any help or thoughts would be greatly appreciated.

Thanks ........
