So, I had that same problem as you all and I did try the solution given by OGGR. It worked once. After seven hours of battling, I finally got in the game with all the mods working fine, or so it seemed. I soon discovered my dragonborn kept getting hungrier and whatever I made him eat, his stamina would keep decaying and eventually, he starved to death and I just couldn't do anything to prevent it. So I tried restarting the game, in hopes it was just a bug. And now when I start the game, I don't have any error message anymore, but I don't seem to have my mods working either. I've tried re-dowloading and re-installing stuff, I checked that all my files were up to date, there's no apparent reason for it not to work. I'm not a modder or very good at all this kind of stuff, but I've spent the entire day researching and trying to figure out what's wrong and I just don't get it.
