As everybody knows it doesn't work....
does anybody know how to fix it?
Only 2 days are left, and my Internet is only a 6000 one.. means i'd need at least 10 hours to download the client.
Help please :/

You can download it starting whenever. If you played in phase 4 you don't have to redownload anything. If not, start downloading now, why not. Pm me if you need a download link.

Literally just took my preorder code downloading the game now. Just keep at it will take some time.
