What does the slot say on the front page when you're logged in? Under the flash deals?
Mine has "Thanks! You will get your game soon". If it's the same for you, you did everything right.

My copy appeared in library pretty soon, but gog did have some hitches with their system yesterday with stamps collection and stuff, and the system is always overwhelmed by big sales.

Probably best to just wait and email them later if the game doesn't appear.
(also, if you haven't played M&B before and are going to, just buy Warband, it's the same game, just loads better)

Yes, it says that I will receive it soon. Well, I suppose I just have to wait :)
I know about Warband, but first I want to try the basic game and see if I like it, then I will may buy it :)

Just thought to mention, because at the moment you have a bit under 2 hours to get the 75% discount. :)

Eh I know, but the situation is a bit more complicate for me than it might appear ahaha, i don't have a really performant Pc but soon I will
Until then, I prefere to rely on free games to test how can be pushed this Pc, one day I will surely buy something from here, it seems really a good service (compared to the console were I usually play, tsk)

In any case, thanks for the help :)
