search3.ppt doesn't seem to work.

I'm using powerpoint 10 and when I open up the search3.ppt, it gives me a message,

"powerpoint can't reach the file...." when i click help, it says "The presentation cannot be opened. Your antivirus program may prevent you from opening the presentation. To fix this problem, make sure your antivirus program is current and working correctly. If the problem persists and the presentation is from someone that you trust, turn off your antivirus program, and then try to open the presentation again. If you do this, make sure you turn on your antivirus program again after you open the presentation."

The search 3 file is only 640 bytes. is that correct? I'm wondering whether it's downloading properly.

when i try it on another machine with powerpoint 2007, a blank PPT file opens and when I click on macro, the dialog box opens but there are no macros in there to run... what am I doing wrong?

Thanks
