Sigh, same problem here. I have the original download version from Atari, with the Enhanced patch installed. I just installed the EAX Hotfix, and now can't play the game at all because it wants me to insert a DVD that, it being the download version, I don't have.Same problem running System\Witcher.exe.There really needs to be a warning post on the EAX Hotfix thread, DO NOT INSTALL IF YOU HAVE THE DOWNLOAD VERSION OF THE GAME.The Enhanced Edition Patch has been a nightmare from day one. First, 2 weeks to get a CD Key from Atari to run the Enhanced Edition Patch at all. Then, months of waiting for a hotfix for the blurring bug that made the game unplayable without giving me headaches. Finally, I check in, the hotfix is out, I install it--and now I can't play at all.A good game has been ruined here by a very poor distribution/versioning system and a debilitating copy protection scheme.Has anyone with this problem tried overwriting the witcher.exe file the EAX hotfix installs with the one from the Enhanced Edition (that didn't ask for the DVD, at least on my system)? Of course the patch didn't back it up, so its going to take reinstalling from scratch, re-activating, etc., to get it back to even try it--wondering if its worth doing so--if the blur bug will remain fixed or does that fix require the new witcher.exe?A game shouldn't be this much work....
