I utilize my laptop to play DVD's for my class. I'm a sixth grade teacher. I use Interactual as my DVD software and usually it works fine. However whenever I install new system upgrades they seem to disable the software and specifically I am unable to project an image through the digital projector even though I can get the image on the laptop.

I don't think this is a problem with Interactual because this also happens with Microsoft media player. My guess is that something happens when I install the system updates.

Any suggestions? I don't want to go back to a previous restore point on my system.

Thanks.
