Here is a short list of our currently known major bug issues:
* Game will not boot. (current work around for this is to go into admin mode to play the game, this will allow you to access all the files you need to play the game properly)
* Game will have glitchy or other graphic problems while playing (look to run the game in windows mode by hitting alt-enter)

We are looking into permanent solutions to both these issues. In the meantime you can look to use the work arounds to play.
