I'm not sure if this is the right post to comment in but I had an extremely positive experience with CDP customer service/tech support regarding this game. I bought the standard retail DVD version of this game late last week. The launcher would not work at all, it kept cycling back from the wolfhead splash icon to the launcher menu.
I looked online for solutions and tried a ton of things such as changing resolution, disabling Anti-virus and UAC, reinstalling, deleting my reg key, adding the patch offline. No luck. I emailed CDP about the issues and basically went step by step through the list of troubleshooting items, most of which I attempted previously but still had no luck, my disks were borked.
After a few emails, whatever issue I was experiencing was concluded as being non-resolvable, and that I would ultimately need to exchange my retail disks for a new copy.
However the part that completely blew me away is that normally for most Customer Service/tech support experiences, that'd be the end of the story. However to compensate for my inability to enjoy the game, CDP hooked me up with a GOG coupon code for the game so I could download and still play regardless of retail exchange. So while it will take 2-3 days to download the game due to my horrible DSL connection, this is still an awesome thing to provide the customer.
So while it sucks that my DVD copy did not end up working, I cant say enough about how awesome the CDP solution was in the end.
