Need help with Led-wiz please

[Connorsdad]

I'm in the process of building a vpin, at the moment I'm setting up the feedback devices using a virtual output kit from zebsboards. I'm having a software issue regarding the leds, they flash once but will not stay lit. Using ledblinky simple led test if I lower the intensity right down I can get them to flicker as you can see from this video. I had them working one minute and then on the next boot I had this problem. If I unplug the ledwiz from the computer and touch a grounded wire to the ledwiz terminals my leds light up full brightness as they should. Any ideas ?

Fixed by running a wire from the gnd on the wiz to the gnd on the flasher board
