Due to some strange shenanigans in the build process, the Windows 64-bit version of 3.1.0 did not start properly. Personally, I blame my archaic game engine because otherwise it would be my fault.
To rectify this, I have replaced the Win64 build with the perfectly functional Win32 version. In my own (brief) personal tests, this was enough to get the game running properly.
[i]Hope that helps.[/i] Sorry to anyone who was impacted by this issue.
