I have installed a pre-configured 1.69 version from a torrent AND bought the Windows version here so I can get some legitimate keys.
I have already sent in a request as per the support topic (still waiting but it's weekend still in Poland so I'm happy to keep waiting) but I have a question.
Are the single player keys obtained with the multiplayer key that i've requested?
They are not showing up in my account as I expected they might.
Do I have to install the GOG version on a Windows install to obtain my keys?
Any ideas?

Never mind... found the answer in this thread.
Wonder if you need a Multiplayer Key now the authentication server is down?
Can I still play modules locally in single player and LAN?

p.s.
I'm returning to NVN after playing the Facebook game... wonder if other people will be doing the same?

Yes.

You need a working cd-key but GOG uses a "generic" key with its normal install....that works for LAN but not for online...
