The Lighting Controller

Take that back..... Xpress plus dongle caused the software to glitch and crash on the second machine.... I'm currently running three of my four universes... Any help?

My xpress 512 units stopped seeing data abruptly. I got a message that I have an incompatible dongle. I have 3 xpress 512 dongles and one xpress plus unit. After removing the plus unit software would start and see 3 universes but no green data lights on the dongles. Switched machines and all ...
