I've just received the game from a friend of mine by the gift mode, but i haven't yet received the cd keys, i have the game installed with the key of the friend, but i can't change them because i don't have the new cdkeys already bought, wtf??

where can i get MY cdkeys?

The installer comes with generic cd-keys that are sufficient for single-player.
To get unique keys for multiplayer you need to contact Support

i've bought it only to play it online :| i've played it offline with the keys of my friend :| i've payed, i want my keys to play online :|
it's not fair to sell a game with the hope that the player don't want to play it online, u all have to sell the COMPLETE game :|

All you have to do is send a mail to them. Plus, it's clearly stated on the gamepage.

this post must be a joke, right?

Not only is it stated right on the game page, and on the support pages, but it has been posted well over any reasonable amount of times on this forum. In fact, it takes about a minute of searching to find a topic that DOESN'T discuss this issue in excruciating detail. Please Chazysunnet, just email them and wait 24-48 hours after that.

Keep in mind that there is no garentee that a person who works for GoG will even read your post. If you want to complain to GoG use the suport links.

If you just want to get your CD key, Here is the link that they posted up front before you bought the game.

this post, and tons of posts like this aren't a joke, if tons of users have this problems i think... it isn't clear the selling method, and expecially, if someone buy a digital copy of a thing, want to istantly have a cd key :/
EVERY site i'0ve bought something before this worked this way......

ah... but... it's written everywhere, it's a fault of mine... plz, think about ur words before talk :/

i've used the support form, this is not a troll topic, end it here ;)
