A friendly warning
May 18, 2011, 1:56 p.m. It has been brought to our attention that some people are attempting to sell The Witcher 2 activation codes without the actual game or the additional content included in legitimate copies. Such codes are of unknown origin, and there is a high possibility that they will not work. CD Projekt RED will not provide technical support for these copies. We advise you not to buy an activation code alone since The Witcher 2 is not legitimately available this way.

My CDKEY is not in the database.
Please send us the key you are trying to use at tw2support@cdprojektred.com.
CDKEY is invalid
Try changing the 0 (zeros) into O (capital o letter, like "okay, now it works") or the other way round
