I'm using MS PowerPoint 2003 on Window XP. From last few days I am having a problem displaying my PowerPoint files. Whenever I try to any one of them I get this error: "PowerPoint was unable to display some of the text, images, or objects as slides in the file (my file name) because they have become corrupt." I have tried several things, like tried to open in OpenOffice Impress, tried to save them with different name. No favorable outcome. Please help me. What shall I do now?
