The one I have has acsetup.cfg and untitled.agr modified on 31/1/2006, but META.exe and winsetup.exe modified on 1/1/2006 (Date created is just now, because I just unzipped it, and date created on the archive is from when I copied over my old files). Do you remember there being any changes to the game between the time you released it and the build you have?
