Hi,

I have a user running Office 2010 that every time they open a given Power Point file it prompts them to repair the file: "PowerPoint found unreadable content in Presentation.pptx. 
PowerPoint can attempt to repair the presentation."
Any help I can get on this issue would be greatly appreciated.

Please help.

I didn't find the right solution from the Internet.
