Okay, I just read through all the previous posts in this thread, and while it seems this was addressed before, but I did not understand the solution, so I'm going to ask myself that someone please explain to my moderately computer illiterate self what to do in retard-style detail, cuz it probably the only way I'll ever figure it out.
I downloaded the file previously posted on this server (at least I think it is, if it is the same file as you can get from this page: http://phantasystaronline.net/downloads.php )
It came in as an .exe file, as I assumed it should, but when I double-click on it, I get this error message:
"This file contains invalid data."
I'm currently running Windows XP 2003 Home Version, I don't know how much of that is relevant, but I figure it might help.
Again, I'm sorry if this makes me retarded, but I really don't even know the first step in what to do.
