Ganglion Not Working Out of Box

Just opened up the Ganglion for the first time. Followed all directions precisely. I am getting this error: ```

    Hi Cartev,

    Have you initiated a ticket with customer support (contact at ? What computer are you using, model, manufacturer, operating system, etc.? Using built-in Bluetooth or the dongle? Have you tried a test on another computer to eliminate issues with your current computer?

    About 12 of the callbacks listed above relate to OpenGL and the computer's graphics driver system. If this is an older system, your graphics driver may be out of date. Check at manufacturer's website for any updates.
