The Lighting Controller

I am running The Lighting Controller and Xpress 512 flickering between scene buttons randomly. I replaced my Xpress 512 box, USB cable, 3pin to 5 pin Adapter, DMX cable going to my Elation Opto Branch 8 and lastly I downloaded the latest Software updated to the newest High Sierra on a brand new Imac and I am still getting a flicker in between button scenes randomly. Minus replacing all the DMX line and the Opto Branch, I'm stuck. I am posing my question for any help, thank you we are desperate to find a fix.

I tried to post video but will not upload

So you have a termination plug on the last fixture of your chain?

It is also possible you have a bad fixture. Try bypassing each fixture one at a time and work your way down the chain (or start at the fixture that seems to start-if that is the case).
