your dad's? lol!! anyway, the 2nd one is a known error, as the first is due to a crap gfx card, or u have "change blend mode if invalid for video card" which is only needed by older cards, if u use a tnt2 or above, try latest drivers..

why dont you buy this game? it's really awesome, i got at about a year and a ghalf ago and damn, i was shocked at the gfx!! anyhoo, hope it all works out good.
