I have a Windows 7 which had originally installed Microsoft office 2010 but just for a 1 month trial so I’ve installed Microsoft office 2003 for which I have a licence. I have disabled the 2010 Office. I am not sure what’s wrong with the PowerPoint but recently it keeps crashing and the following message appears: “PowerPoint was unable to display some of the text, images or objects on slides in the file… because they have become corrupted. Affected slides have been replaced by blank slides in the presentation and it is not possible to recover the lost information. To ensure that the file can be opened in previous versions of PowerPoint, use the save as command and save the file with either the same or a new name.” – When I try to save under different name, the problem still persists. Moreover the presentations changed and all of the slides have the borders and lines, when I’m trying to clear them (no fill for both: lines and borders for every single slide) the presentation not responding and crashes. Also the master slides are different to the slides; my logo at the footer disappears…this is so annoying and I really don't know what might be the problem, especially for the borders and lines that are now visible and spoiling the presentation.
I’ve been thinking of reinstalling it but not sure if this will help.
Can anyone please help me?
