I have a Mac,so that didn't work....but....went to disc utility and erases the files and re formatted the glasses. Work fine now.
I bought the IKAM glasses, won't do that again. Aside from aiming problems and an extremely sensitive mic, on a cool day they can break really easy, and a single minute of accidently looking in the direction of the sun can damage the camera to the point the picture is not that great. Here is an example after the sun damage..
They worked ok for me, but I got a GO PRO hero HD nice video.

Tried IKam Extreme for a weekend and sent them back. Glasses were poor quality, video flickered and jumped when I downloaded it to three different computers.
