Problem with eb1.0

[Stone and Blood]

I renamed it, now is C:\EB10

Another strange thing that hapens. I start the game and apears the screen with europa barbarorum, Total War, Creative Assembly, etc... But when the game starts loading, all the screen become Black and all i can see is the green bar growing at the lower part of the screen, loading. Then apears the menu screen. Then i start the campaing and all turns black again, and all i can see is the green bar. When the loading finishes, all turns back and the lovely CTD shows himself.

I can't install the 0.81aV2 again. When i open the instaler, it says that an error ocurred because a superios version of Europa Barbarorum is installed. But anyway, as you changed the preferences to the lowest possible, how could the 0.81aV2 preference make something?
