If you cannot register game you cannot download the Enhanced Edition. When you have the registration code on thewitcher.com there are the instruction about how and what to do to download and install the pacth.Anyway, you should first download the Language pack and then download\install patch 1.4. This two should update your game to the Enhanced Edition. I highly reccommend to install this patch 1.4 because it reduces you loading time of about 80%.cheers
