Why can't you play?  There's a thread for hardware &amp; compatibility issues here:
http://utforums.epicgames.com/showthread.php?t=578480
the first post has the solutions/workarounds that have been working for most people but not everyone.  My UT3 beta demo will only run in windowed mode using the binit=True fix and even then sometimes the game won't start again (usually after my screensaver has run I think) and when that happens a random change in the ATI options will get it back usually - if that fails a reboot will definitely make the game work again.  There's several ini files in 2 different locations and if you go through all the posts in that thread it would seem there are just alot of stupid ppl or the beta demo actually doesn't unpack/install all the ini files for everyone.  I had the beta demo installed for almost 48 hours before I was able to play it because I couldn't get past the opening splash videos and into an actual game screen.

Of course, now that I can play it I freakin love it  :D
