Yep, same problem here. I'm not going to lie, my first experience with GOG has not been very pleasant.
fjdgshdkeavd: Don't worry, they'll fix it. It's not supposed to be up until tomorrow anyway.
Note also that gog is literally charging 1/4 of the price that Steam is charging.
Oh, it's not going to put me off from using GOG in the future. I'm simply stating that my first purchase has not gone as smoothly as I had hopped.
As to when it's supposed to be up, I would argue that as soon as it changed over from "coming soon" to "add to cart" was the correct release date. One could also reasonably assume that a polish company would use CEST when determining what "tomorrow" means. In that case it has been "tomorrow" for several hours. It may still say "tomorrow" but that would imply that it's not coming out until the 11th, in direct contradiction to the information that have released previously.
That being said, I'm not going to throw a hissy fit over this, I have played through the game before and I have a physical copy sitting around my house somewhere, I'm just too lazy to find it. So I figured I would kill two birds with one stone so to speak, support the developers I love and get a digital DRM free copy.
