So, I've tried to download this via the downloader twice, both times it got interrupted by some error E1014 (couldnt get it written down before the text vanished). First time was at 60%, other time at maybe 10%. Sadly the downloader restarted the whole download.
Then I tried the 3 files, first (small) one, no problems. The other stopped at 5%. The third one stopped at 6%.
Bought a game before that I had no problems downloading.
Edit: Now third time downloader got the error, and as before the queue is empty afterwards.
Edit2: Well, seems like the downloader decided to work during the night, so hopefully I can just install the game now. :)

I tried and failed with both the GOG Downloader and another one, in the end it was the GOG one that managed to come through. :)
Not that it matters anymore for this game, but would be nice to not have the same problem with the next one I buy.
