Anniversary problem. Enter button not working PC

[Vultura]

Hey All.

I've recently re-fallen in love with Lara Croft and wanted to get back into the games. So I went out and bought Anniversary for PC. I am running Vista with more than what is required for the game.

But I'm stuck. In Persia - Lost Temple, I am at the bit where I am required to place the cog on the stick. But when I select it and hit enter, nothing happens. It's not recognizing it.

Know how to fix?
