Wings Of Honor: Loading ' Battles of the Red Baron' - Wings Of Honor

Has any one had problems loading and playing the game. I get to the options screen,choose 'Flight Sim' or 'New mission' which I play for maybe 10 secs then I get a blue screen which comes and goes so quick i can't read it and then the computer re-boots. And thats it. My computer has been 100% reliable up to now. Plays 1/2 Life and C.O.D. no problems at all. I will go into computer spec detail if there have been incompatibilty problems in the past with anyone. Any help out there at all please/ Andy Barrelroll
