OK, 2nd request sent. I know my e-mail address is correct b/c I get the sale ads. Why can't they just provide these when we purchase the product? Is it really that difficult?
And why is the CD request link accessed through a forum post and not available from the title on my shelf? I think this may be the last time I purchase from GOG b/c they don't seem to have their act together and are totally unresponsive to customer requests.
To answer your questions:
GoG does not automatically give out the CD-keys because a) they have a limited amount at any one time, and automatically giving them out could mean that some people might have to wait just as long anyway and b) they want to provide their games DRM and copy-protection free, putting the CD-Key with the game prevents this.
The CD request link is also available through the support page for the game(the same with any game that needs a CD Key), and I'm pretty sure that it states this on each games page.
It is true, from what I hear, that they don't answer their support emails as well as they should, but they are still a relatively small company, and besides, some of the people in these forums are often far more qualified to answer questions about specific games. You have to remember that GoG does not make them nor do they necessarily play them, so you can usually get FAR better support just by asking here on the forums.
