--Stormy--: I have the same problem but somebody complained about it and they said it had to uninstall and download the whole game from Gog but from the browser not through the application Gog....
And they say it works then without any problems so I'm going to try.
mehmetfuat: I just uninstalled and downloaded it back from CD. It worked but not sure the update may come back.
It's just that he downloaded the game from the browser, and that update too, and everything was going as it should.
I have also reinstalled the game forbidden update and the game works fine but how it will begin to update so it is final and the game does not want to turn on after the update is canceled.
I'm going to try it through this browser because the CD version does not get the update.
And there is one more option that I've come across and that works for me to look into the settings there click on the download and check where your game is located and where the gog is.
Procedure: Settings, Downloads: Game installation folder and Other downloads folder to check if everything is placed correctly if it is not so much editing and it should turn it to me it needs to work now with updatem i have it installed and the game works If this does not work so do what I said before .....
