JudasIscariot: Please contact our Support department. Don't forget to detail the problem as best as you can and please, please, please make sure to send a DxDiag file along with your email.
tarangwydion: Many people actually encounter this bug. I won't complain much, after all I did finish Gorky 17 GOG.com version. I either skipped the intro or replaced the movie file with something else.
It's been going on for years actually:

Like I said before, please send emails to Support, along with a DxDiag, about the particular issues with Gorky 17. The more information we have (DxDiags are a big part of that) the higher the chances are that we can work towards a possible solution for this nagging problem. I can't guarantee an immediate fix, but getting support tickets through the official channels helps us keep everything in place.
edit: Please keep in mind that we do not have access to the source code of any our games, thus, it takes a lot more time and resources to fix issues that crop up.
