I have been able to download all the other games that I own, but for some reason GK3 won't start at all. I have tryed everything what the support page suggest but with no luck. If anybody knows a solution or have some tips or tricks let me know. Thank you.

Have you tried using just the browser to download the game?

Ahh, well the downloader at the moment is fairly buggy. You could try a 3rd party program like getright on the browser download in the future. The only problem is I think I remember people saying you had maybe a day or 2 to get it before it could no longer find the file path. But if you are able to get the file within a day this should work even with a connection that needs starting and stopping.

I'm having the same problem.

I have the same problem. I add the game (GK3) to the Gog Downloader queue but it doesn't show up after refreshing. I just tried GK2 and that worked fine.

I also have the same problem.

Unfortunately this just seems to be a problem with GK3. I was sending messages back and forth with a gog technician when suddenly the game downloaded. Our conversation ended without any real explanation for it. I think you just have to keep trying... doesn't seem like gog has an explanation for why the game won't download through the downloader at times.
