Cataclysm download not complete

Hello guys,

I just downloaded the torrent client from your website and started the game. It said that I have only 59% of data downloaded yet. So being a smart boy, I opened the background downloader and let it download through. It was at roundabout 9,3gb of 15,4gb.
So after I started the game it still said that it has only 59% data downloaded yet although I downloaded almost 6gig stuff. I found out that the downloader only downloaded data into the "TempMig -> 5.0Migration-data" folder".

So does anyone have a solution for this problem?
Is it like that because I downloaded the german client and should've left in on english?

greetings
