I just downloaded the game on 5/1. It was version 1.0. I tried redownloading for the update but it is still 1.0. Is there a link somewhere for the update. I tried googling for the update but could only find it for Mac's.

Did you install it and look at the main menu for the version? The download says 1.0, but when installed you'll have it read 1.00.04

Please hit your "menu" button. At the bottom left hand side will the be version number.
