Download Microsoft's online game platform of X LIVE and register an archive number (if you have not registered for online photo tutorial). It's simple. If you don't register, you can't file.

I looked at your configuration. It's hard to play Biochemical 5. Maybe I can't play it yet. Is my 8600GT still a card?

In addition, give a download address of X LIVE:/pcgame/pcgame/download/4655.html.
