Glo Pc not recognising?

Just bought mum a Glo for her birthday and now trying to connect it to the pc but it doesn't do anything. The screen on the unit claims it is connected and charging but nothing installs and nothing appears in my computer (windows 7).

Tried different cables and Usb ports to no luck. Also downloaded the desktop 'app' in the hope it may have drivers.

Is there something simple I'm missing?
Please help!
Thanks,
Matt
