OK this will sound really weird but I'm having some trouble installing a few extensions. I've DL'd some extensions that have the options: "Run" or "Save", and I maneged to install THEM.
However I DL'd the Perspective obj And it had the options: "Open" or "Save". I saved and opened it, and in it was the file called "Perspective.cox". I double clicked it and it came up in MS Wordpad! (Or something like that) I can't figure out how to install the dang thing! Do I need to put it in a directory, or do I need to install it? If so... HOW do I install it?
