OK, just for everyone who missed the answers previously, I'll try and sum up what some other people have mentioned:1. The only people who need the patch are the ones who purchased and installed the North American retail version of The Witcher Enhanced. a. If you purchased the original version and downloaded the 1.4 patch, you don't need the file. b. If you purchased the retail version of the European retail version of the Witcher Enhanced, you don't need the patch.2. If you are unsure if you need it or not, go ahead and get it. It isn't like the 1.4 patch which is very large. It is a tiny file, smaller then many images on the internet. You can grab it in just a second. Since it does a check before applying the patch, you can't hurt your game by trying.Lessjake:I'm not positive, but it almost seems as if you are talking about the 1.4 patch. I don't recall the Blood Patch verifying you were registered, but since I was logged on to the website at the time, I may have missed it. Also, it doesn't seem to check the language pack, it only checks if the missing file is there or not, and adds it if isn't there. If you are talking about the 1.4 patch, you may find more help on this thread: http://www.thewitcher.com/forum/index.php?topic=16804.0
