There was an issue with Windows 8.1 that prevented the game from running. This has been fixed by adding the VC++ 2010 redistributable to the install.

A side note on the OSX version: newer versions of OSX depreciated key library functions that cause the 2.0 update to not work on anything past 10.6. The fix requires changing the graphics libraries for the game, which would take a bit of work that I haven't had the time to do.

Thanks, Brandon Brizzi
