User blog comment:Ausir/The Witcher 2 first patch released/@comment-80.79.208.20-20110518132835

The problems people were having with not being able to run the game for the first time or register DLC last night were due to the server hosting the Witcher 2 files being taken down last night for a few hours. The official pages said that this was to fix a fault people were finding and build a more robust server. I luckily managed to register and get the patch/DLC just before they took it down for the maintainence.

I find it strange that the server failed so quickly upon release of the game though...someone will be currently standing in the boardroom of the developer trying to explain to a lot of angry directors why this happened I'm sure!
