Boox does not work

Yesterday my Onyx Boox Note arrived and I have already had some problems that it constantly hang-up. When I tried to use the device today, it did not even started and even after trying to charge it (actually it is supposed to be almost 100%) it has not responded in any way. I have bought the device via amazon. Have you got any suggestions? I could not find anything helpful when browsing the forum.
