I didn't think 1.4.1 was ever made. 1.3.1 was pulled because some *a-hem* one complained it showed as a virus by some antivirus software. People have periodically asked for these files time and time again with no results. Of course someone has the file, probably, but not RDkill.
My advice, await SHC2 and hope they add the stuff people want in a game i.e. multiplayer w/AI enemies.
