PowerPoint 2010 – some controls on this presentation can’t be activated.

PowerPoint 2010 – some controls on this presentation can’t be activated.  They might not be registered on this computer.

Hello Experts,

Here’s the scenario: I’m embedding a flash video (.swf) file into a slide.  I can do it using the Shockwave Flash Object control in PowerPoint. The problem occurs after I save the PowerPoint file (.pptx).  When I try to open it again I get a message stating that PowerPoint found a problem and needs to repair the presentation.  If I click on repair I get the message: some controls on this presentation can’t be activated.  They might not be registered on this computer.

When I then open the slideshow the video does not load.

Any help would be greatly appreciated as this is a presentation that needs to go to a client asap.  Thanks!
