Here is the direct link to the patch for us folks who are having launcher issues. Register your game first or else it won't let you view the thread or download it. I won't say anything but look at my signature. Not that I'm accusing you of anything, ha.

That's a completely unfair assumption, I paid for the game just like everyone else. Only problem is I can't find the box for my EU3 disks, and it appears registering those disks is what is needed to access that forum that you linked to. I haven't had problems downloading patches from the launcher in the past, I would just like to know why the launcher update isn't working for this patch, and if it ever will work.
