Charged as a trial and installed on FIRE TV. While my wife on the box looks a series, I sit next to it and check my emails. Get at once a message that I have purchased a full version. Soso ... at 72 cents no big deal, who cares if it would have worked in the test, I would buy it anyway. So I try the same times the now already existing full version. Result: No function, crash, once the iPad, the first image to be transmitted to the pits. Conclusion: Thanks Dipendu Saha, my Voruteile certain "IT specialists" opposite have been confirmed, hopefully you can buy a great thing of the fraudulently obtained 72 cents.
