I could not get the Demo to work, but I purchased the game anyway. It looks like it should be relatively easy to get to work. It only requires XNA Framework 3.1. We have a crosstie for XNA 3.0, but XNA 3.1 installs well enough. (Crosstie for XNA 3.1 will be added soon.)
Additionally, I found some references to MS VC 2008 runtimes, but installing those still proved unfruitful.
Debug log will be uploaded soon.
