As some of you may know, The PX website was recently attacked by hackers. As a result, the forums are down. The main page is still there, but the download link there is wrong, possibly because of the hackers as well. There is no ETA on when the site will be back online, but while it gets fixed, if you still want to download the game, then I have a mirror link here you can use to get it. It's still Windows only, as the Mac, Linux and Wii ports are still not ready. Hopefully the site will be running again soon. Thanks for understanding.
