I had huge problems getting the download of the beta started anyway, and when it ran (and told me 12 hours to go) i faithfully let my PC run over night and went to bed.
But of course it couldn't be that easy. During the night my Internet Connection got cut off, and now i can't download at all.
And when i try to initiallize a new download it keeps telling me my key is in use...
So what can i do now?
