I cannot figure this out! At our last wedding, our CyberSync CST's stopped firing our AB800. I set it up, everything was working fine. We came back after portraits and it wouldn't fire! When I hit the test button on the CST, I see the receiver light blink, so I know it's communicating. And when I hit the test button on the flash unit, it fires, so I know the bulb isn't dead. So what is it??? We recently got the new 580EXII flashes and thought maybe they are interfering because sometimes they will fire when the test button is pushed on the CST's. I don't know, it's baffling and frustrating. Please help!

Ok my genius husband helped my stupid self. It's the Mono sync cable, he just moved it around and it started working, the cord is going bad.
