Well lets start with the problem, First post your App.log so we can see why the game is crashing (in the game folder it should be there after u ran the game and it crashed), This should give us a better idea of what is going on and hopefully it will be fixable without you having to install another OS,
But if you do decide to install another OS i recommend using Ubuntu, you can install it inside windows and dual boot with windows so you can still keep your W2K3 OS and have Linux as well.
