Hey guys I just spent a few hours troubleshooting the registration problem. Basically I'm running windows 7 and reinstalled the witcher, but could not install the patch due to the registration issue with enabling cookies. After messing around with a bunch of technical fixes I remembered in the past it is a time stamp issue with the cookie. If your time or day is wrong in windows it will misread the cookie timestamp and your registration will screw up. MAKE SURE THE TIME AND DATE ARE CORRECT OR YOU WILL RUN AROUND IN CIRCLES FOREVER. Hope this helps someone.
