It says to run the installer's integrity check to verify which files need to be re-downloaded. Is there a way to actually do this for other games? I'd like to check some game's integrity before i back them up and not all games on GOG seem to verify integrity before install.

Im having the exact same problem right now

Same issue as of last night. About to try for third time.

Have downloaded to two different drives and used both the GOG Downloader and Firefox.
I have never come across this issue with any of my other games and installers.

I have this problem also. I've re-downloaded the files four times.

Same problem here. Bah.

error "The Source File is corrupted same for me dont work :(

I changed the name of the file (seemed to get past it), but then it asks for the folder with part two in it, when I gave it the path to the folder it says it isn't there. So, no luck. :(

Came looking for this issue and wasn't disappointed.

In my case, since I couldn't find a way to check the integrity, I deleted the folder and redownloaded. The game will redownload through the downloader but the accessory pack will not at all. I'll wait until the overall fix to try again before putting in a ticket to see if that fixes things but thought I'd mention it.

Same problem. Source files are corrupted.

Heh just got up this morning over here and decided to check this thread. Thanks for the info Judal at least we now know you guys know there is a problem and that its going to get sorted. Going to go play NWN2 then which I also got in the sale =)

Thanks for responding to the thread with the info. Looking forward to the fix on Monday, have a great weekend.

EDIT - Looks like they've fixed it!

Thank you for information :). Luckily, I did get plenty of other games from the promo (which was great, thanks!) so it is not that big problem for me.

EDIT: It seems that problem is fixed now. Thank you for quick action :)

Yep, it's working.

Thanks for the service.

doesn't work for me
to clarify this is what happen when I run the freshly downloaded installer(have tried redownloading several times and also right now) and I quote:

C:\gog games\neverwinter Nights Diamond Edition\2dasource.zip

An Error occurred while trying to read the source file:
The source file is corrupted.

You should run the installer's integrity check to verify which files need to be re-downloaded.

click retry to try again, ignore to skip this file (not recommended), or abort to cancel installation.
