So I did not have ByteFence Software installed and no Anti-Malware and whatnot and still got the same problem when Downloading v1.12. So what I did is JUST HIT THE DOWNLOAD BUTTON again and again. This is obviously totally unreasonable but it worked. For some language-packs I had to repeat it 5-10 times but finally I got them all downloaded and can play v1.12 now. Hope it works for you too.
