Problem is solved, I let my computer download the whole night, and yeah the download had already finished.
But, I have a second problem now:
It's no problem to play the game, but there is still an update left, so I can't play the game on internet.
But if I try starting the download it stops by 1,6%. Then it says retrying and than Error.
Always, I've tried it more than 5 times!
Hopes this problem will solved himself too, but i don't think so.
Should I do the same you have described in your first post and send it to the support or is there another solution?
I've already tried to close my firewall and my antivirus protection, but it dosen't help!
