I didn't post the PK OS update because I hadn't tested it myself (no PK). However, I just found where I got it from: https://groups.yahoo.com/neo/groups/p2k/files . If Ray's site successfully updated your PK, you don't need that dll, but since I just stumbled onto it, I wanted to post the link.
As for the mythical 1.07 dll, just a guess, but I think that is a rumor that got started by a typo or something. I don't recall anyone saying they ever had it. If I am wrong and I spot it, I will be happy to stand corrected.
