I recently bought Civilization 4 Complete, and when I'm playing some of the Beyond the Sword Content, such as Final Frontier, Rhyse and Fall of Civilization, or Gods of Old, the units are invisible, and the city will show up but not it's name or the city window when I double click on it. I assume it's fully patched since Civilization 4 Complete contains all the Civ 4 stuff to date, but does anyone know of a fix or at least a reason why it's like this
