Deus Ex

I have a pretty new computer, and I've been trying to run the game Deus Ex. But, it shows some weird error:

Geneport I/O Initialization failure.

And then I can only run the game in window mode, and it's very annoying. does anyone know how can I fix this?

Try flipping it between Direct3d/OpenGL/Software rendering.

It worked, thanks.
