PowerPoint Corruption Error Message

[Pard10]

I am using Office 2003 and keep getting error messages in PowerPoint which
say "PowerPoint was unable to display some of the text, images, or objects on
slides in the file, "xxxx.ppt", because they have become corrupted. Affected
slides have been replaced by blank slides in the presentation and it is not
possibl to recover the lost information. To ensure that the file can be
opened in the previous versions of PowerPoint, use the Save As command (File
menu) and save the file with either the same or a new name.

There are no blank slides in the presentation, so nothing was replaced. And
doing the save as does not clear up the problem on the file, get the same
message. How do I correct?

You might try round-tripping the file through HTML. Instructions here:
