Method 3: Remove all Auto-recover files.
One or more corrupted Auto-recover files may be on the system, and may be preventing PowerPoint from opening your presentation.
For PowerPoint 2008:
PowerPoint 2008 saves the file in the Microsoft User Data/Office 2008 AutoRecovery folder with the name "PowerPoint Temp." Move these to the desktop. You can review them later to see if they are important.
For PowerPoint 2004:

After you click a presentation in the PowerPoint Open dialog box, PowerPoint displays a thumbnail of the first slide. If this thumbnail is damaged PowerPoint may not be able to open the file using this method. Try a different method.
Method 3: Double-click the PowerPoint presentation.
In the Finder, double-click the presentation file that you want to open.

If you are able to open the file, search the slides for any blank object place holders and delete them. Re-save the presentation, return the file to its original operating environment, and then try again.
