unable to create direct 3d9 device?

 From:  jacobo3d

I'm having this problem too. I was using MoI in this laptop (graphic card is GeForce Go 7400), and it was working with no problem. Suddenly, I just open MoI and the "Unable to create Direct3D9 device" message appears over the viewports. I didn't change any setting in my video card... It was working, I've just closed MoI... reopen it again a few seconds later, and this is happening.

Any idea about what kind of problems could cause this situation?
