What server/computer should I run FrontDoor with Cablecast and Carousel on?

Hello Everyone, I have the SX2 setup and when I go to the FrontDoor and into the server setup and then in licensing, It shows, could not read license data. The provided license key does not appear to be valid.
When I go on the Cablecast Pro VOD and into the same licensing screen, it shows everything that I have. Now should I be running the FrontDoor with the Cablecast, and Carousel on the ProVOD or the SX2??

Thank you,
Jon
