I've complete closed out the downloader from the system tray in windows 7 and reattempted download 15 times. Any ideas before I just delete the files and start all over? Thanks.

I have exactly the same problem when I use IDM to download the file every file stop at some point now I've use FF browser to download again seem to get pass on stuck point 1.3GB/2.0GB atm

I found a solution on another thread, an answer by Aerials1:

i had a similar problem

basically delete one of the chunk files (50,200kb) and remove the witcher from the gog downloader, re-add it from my account and it should redownload and re-combine the broken parts


Now it works for me, woot!
