Completely chaotic and insufficient ..

Buy game on Friday, tried on Saturday to install message: Key already exists. Friendly foreign service staff from Monday evening 17 clock to 20:30 clock employed to purchase note and photograph of packaging to send then to get a new key.
Then intermittently to load a day an update and 4GB for an extension ...., though after installation is a screen but no one says a yet experienced FPS players we like now the game begins by me? Since a cursor blinks for hours but nothing happens ?? Until now 4 days to a game to get going and there are probably even more? If one reads the whole error messages in various forums that can still come I do not understand the positive comments here ...
