I've made lots of Power Points for school and usually I insert an embedded youtube video into my power points.



Recently, the videos on the power points that have worked before on my laptop computer are no longer working.

I took this exact same file to my school to my school computer, played the power point, and the embedded videos work! I just don't get it. A month ago on my laptop, they worked just fine. The videos on youtube still exist. I upgraded flashplayer. I upgraded my system requirements. Even still, when I play the power point from home, when the slides with videos come up... only a blank white square appears.

Any ideas? Has anyone had this issue and been able to fix it?

My laptop has Windows 7 and MS Office 2007. The computer at school has the exact same OS and MS Office.
