I am receiving an error on a file indicating there is a problem with one of the links.

To my knowledge I have not linked to any outside file, I have not Dragged and Dropped a file or pasted a file into any page. I did insert a .ppt shape from the ribbon by dragging it to the sheet. I have not changed any location within the PPT program so I don't know if this would be the source of the broken link.

I opened the .ppt file to view the xml code trying to see if there were any links and I didn't see any references to outside files.

This appears to be more of an annoyance than anything else as an examination of each page indicates it is complete.
