Windows 7 64 bit, dual ATI 5850 cards - can't view game map
All of the title screens, dropdowns, interfaces et al. show up just fine, but the "zoomed in" map is completely white and nothing is visible. When I zoom out to what I think is the cloth map, it appears in the negative as a black screen; I can see my hero and a few other things. Changing the brightness, as recommended in a different thread, did not solve the problem. Obviously the game is unplayable in that state.
I have the latest 10.7 ATI drivers, and also reloaded the older 10.4 driver in an unsuccessful attempt to make this work. It sounds like other W7 64 owners with ATI cards have had problems, but I don't think anyone else has reported the same problem as yet. Any help you can give would be appreciated!
