I want a lot about the game not reveal, actually still give tips:
First: Invite not shut the version of Amazon. This is 5GB in size and not compatible with UPlay. This means that although you can play the game offline, but it does not play online, even patch it can (and just the erstesn patches fix error very arge)
The best code simply register with Uplay and then the 12GB big (!!!) variant download directly from Ubisoft, this is then already each patch included.
It is also important that the patches that there & M page does not automatically UPlay, but on the official M, NO are patches for the release version, but for the beta that was released.
Patches 1.1 - 1.22 will bring you nothing, as this - as I said - are for the beta version. So you save the downloads.
This jumble of versions is also the reason for the 1 star deduction. Thought it was rather stupid, for a week long search for a solution and then to come up by chance on it.
