You've tried a fresh download of one or a few of the files that are giving you a hard time?
We're talking CC here, right? Not actually mods, right?
A few 'hundred', *gasps and keels over backwards* I'm such a NoOb at this CC business, lol. I think I have, what, 50 items altogether?
*edit* Oh, if you could share what a few of these files are, I could try putting them in my game and seeing if I get the same message. At least that way we can rule out the file itself if I have no issues installing it.
