Age of Aquarius has been updated to work with the new 3.6.12 MediaVPs. In order to prepare for the imminent release of War in Heaven, you must download this update as well as the new MediaVPs and a 3.6.12 Final Inferno build.
If you don't want to redownload all of Age of Aquarius, visit the Blue Planet download page at Hard Light Productions and download the Core, Visual1 and Visual2 VPs.
The ModDB version of the campaign has been updated to include the new files.
