Original Skies of Arcadia, font problems, help?

Got original skies of arcadia, borrowing from a friend, but, when i put it in my dc, it boots fine, but the dialogue is huge, the font is horribly skewed and i cannot read it. the problem is my machine, but i have no idea what could cause this. it is unmodded, orginal condition, 1yr old, anyone have any clues???

thanx
