problems with the icon artworks and eyes of leaderheads

[CivArmy s. 1994]

as u can see on the images, the eyes of any leaderhead of the game has this white spot and the icons look strange, they r small then suppose to be and with bad resolution. it starts to happen these days and I tried restart the game several times. anyone can help me?

I think I remember seeing somewhere that the small icons were due to unmerged .dds files... have you played with the icons at all before now?
