Can't run any of the sets

[oldrocker99]

When I try to run Overture, my screen gets enormous (same size, but everything is huge and I have to scroll around my desktop.) I have to log out and log back in to get back to a normal-sized screen., and Overture doesn't start.

Here's my hpl.log:

I have libopenal installed, along with all PulseAudio extensions. Any help here? I had played Overture some few years ago, and it ran fine.
