Default Cannot see truesmart as mass storage device

yesterday I received my Truesmart but before doing something I've just played with it as it is.
I did some photos and videos just to see the "quality" but when I connect the smartwatch I cannot see anything.

If I move the mouse over the unplug icon on my pc I can see two letters added like disk drives, but these new units does not appears on "my computer".

For now, no microsd card was inserted and I'm using internal memory to store pictures

What can I do?
