For some reason the last two patches have resulted in the pictures not being visible. The pictures are pure white with maybe a single line or two which can be seen. The graphics and units on the map all look correct... it's only the pictures like in the very beginning when creating your sovereign.
I'm using WindowsXP_64bit with a 7600GS graphics card. I've tried the most recent drivers for the graphics card and older drivers yet still the same result.
