pv2+

Hi guys, No matter what I try my pv2 + simply won't connect to Naza M more mater how much I try. I keep hoping to see the blue light flash up at the bottom left of the screen but it never happens? I'd be very grateful for your help and ideas. Thanks in advance. Ps I'm running Windows 8

Hey guys and gals, I am parting out my 2 year old, never crashed, P2V+. 2 Batteries which hold charge as if they are new. I never short charge them. All of the accessories that came with the unit brand new. I'm even selling off the custom hard case. I bought a new unit and don't want this...
