Hello there, I don't know if you'll see the picture attached (it seems that there is a problem with that...) so I'll try to be clear.
Since the update to 1.61, I couldn't start the game because of some mods so I uninstall everything, downloaded the files to install it offline, and install it again.

I thought it was all good (I didn't install mods again), but no.
GOG should have downloaded a small update of 504 MB but seems to be unable to do it. It tries to download the files, but when it's up to 96% at the step of "Execute installation" (crapy translation sorry, it's in French for me) it crashes. And then GOG does it all over again! Again and again, failing each time, thus I can't even play anymore.

I don't know what to do. I even uninstalled GOG yesterday and installed it again, but the problem remains. I tried to send a ticket to GOG via chat, but it doesn't work... I really don't know what to do anymore.

Thanks in advance for your help!
