Anyone else have issues with their controller, I dropped $1100 on two vega fixtures and the controller. I'm on my second controller and right out of the box with the new one today ALREADY needs firmware updates and has lines running across the screen. Plug it in to update and computer won't recognize anything is plugged in. BY FAR the biggest head ache and waste of money ,the lights are great but useless without the controller. Anyone else having issues?
