A problem occurs in opening the ppt with multiple graphs once it is saved. Whenever I try to open that ppt or mail it to somebody and that person opens it, it asks to repair the ppt. If "cancel" is selected then the ppt does not open and if "repair"  is selected then it repairs the file in which it places a red cross on majority of the slides and the slides appear blank.

i am using powerpoint 2013. This issue happen in only some of the files. File format is .pptx I have added graph from my laptop itself. when i am trying to open that file in office 2007 it is opening fine there and i am also able to save the file. And this same problem is coming in few users. Even if they make a new file the same error is coming with the powerpoint 2013.
