Until the site is back up, feel free to use this download: [removed due to creator's return] Of course, since it is not the official download, it is wise to be skeptical, so make sure to scan it with your antivirus. Yes, I uploaded it myself, but I'm not expecting you to just take my word for it being safe.
CaptainChaos, if the site is gonna go back up, feel free to notify me and I'll remove this post.
The file is digitally signed by pepsoft.org on 02/05/2017 and did not trigger MBAM, so I'm seconding the legitimacy of this.
Edit: aw crap. Looks like it needs to download libraries or something. ZIP up your install folder contents maybe, try something out?
Second edit: Just click cancel when it complains about internet connection, it works.
Third edit, Chaos returned, pulled link.
