update

Hello, today I bougt the minikit slim.
I dowload the software opdate tool en after a while he reconice the device. Thats all, after that nothing happens.
The sending updater does'nt do anything even when I wait one our.
on.
In the quick start they talk about reset the device, and to do this I must do this with the reset button ad the back, well I can''t find this button.
Anyone a idea what to do?
