I created a PPT (2004/11.6.4) slide show last night and tried to show it at work today.

The slides did not show up. I could see them on the preview on the laptop, but then when I opened up the slide show there was neither text visible on the laptop nor on the video screen it was being projected on. It also looks fine on my desktop, which is where I created it. I did it on a Mac.

Can't figure out what went wrong. Anyone have any ideas? Thanks.
