Bino's have you thought about trying Open Office instead of Microsoft Office

I can't say how good it is on a Mac, maybe a Mac user can, but it's fine on the PC and it's free. I've just read the instructions on using it on Mac OS X, it seems complicated so maybe better to stick to trying to get MS Office to play the game.
Mind you did anyone imagine that Microsoft could get their office suite to work on a Mac. They have enough trouble with Windows.
