Important! This patch can only be applied to v6.40. If you try upgrading any other version you will end up with a lot of error 91s and have to Ctrl-Alt-Delete out.
This is
NOT a database patch so if you upgrade you won't lose your saved game. Just unzip the Aurora.exe file into the installation directory, overwriting the file of the same name.
