Ranged download is currently ignored!

My connection is pretty unstable (but quite fast). I've downloaded my game 4 time already, every time i restart from scratch....
I've tried the air client too but it doesn't change much, still from scratch :(
please don't do a single shot download link but create a temp link (6 hours?) so resume would be possible or at least find out a way to accept partial download!
cm'on i know you don't have anything better to do xD

You could try using the official downloader unless you're allergic to (one hell of a condition, that). And even then you could use the [url=http://www.gog.com/en/forum/general/jgogdownloader/post1]JGoGDownloader if you have nothing against Java (personally I prefer tea to coffee).

The latter of those even downloads all the extras for you.

Edit: Oh, bugger, I didn't see that you tried the official downloader. Try the unofficial Java one I linked to.

To be honest i'm allergic to them both, btw neither of them works as it should, java client just keeps saying "Could not get the lenght of the file." and air client doesn't resume the download!

Hmm... there's a more complicated route, which some people have had success with (I haven't tried it myself).

1.) Export your cookies (ask google how, not me)
2.) Get another download manager (Free Download Manager, perhaps?)
3.) Fetch the link to the file you're trying to download (in the form of www.gog.com/en/download/game/<game name>/0) - with /1, /2, /3, etc for the bin files of multipart installers.
4.) Import the cookies file into the download manager, feed it that link, and off you go.
