Collector's Edition USB

Awhile back the USB portion of my Collector's Edition plumbob broke (now I just have a sad plumbob). I know that there were files on it, but I can't remember what they are, nor do I have a copy of them. I was looking for where I could find a lone plumbob, but I can only find full Collector's, which I don't need and I don't want to spend another $60 or so on it. Does anyone have any suggestions for what I can do about it? Is there a place for the files? (Again, there are files, right? Or am I delusional).

And sorry if this isn't in the right place.
