why isn't my game working

I am having trouble with a game. The game will not start due to my computer not being able to load something called a “open gl.”
I have a voodoo 2, and window 95. Your website says to go to “win.ini” and change Dva=0 to Dva=1. you see I don’t have any dva’s. what should i do? please E-mail me at lk9t9bob@aol.com. thanks
