OK, I have found the appropriate archive. How do I open "user.setting"? It's obviously not a .doc file...

I'm trying this hack right now, but I have another problem. I go to C:\Documents and Settings\yourusername\Local Settings\Application Data\Ironclad Games\Sins of a Solar Empire\ ... but then I don't get any "settings" archive. What am I doing wrong?
