I,m using a Toshiba "Satelite L305-S5968" Laptop. I bought a Phoenix flight simulator - When I tried to install it the computer said I need "MIcrosoft DirectX9 or higher". My question is what is it, and how do I get it? Thank you. Oh, and this is my 1st computer and I really don't know what I'm doing with it. LOL. I do know how to use a slide rule but thats not much help anymore. Nick
