I have a problem with all my Power Point presentations that I created with the 2003 version in 2010. I am using Windows 7 as an operating system.With all the presentations is incorrectly formatted after opening in 2010 of the Power Point slide masters shown (the footers seem completely wrong to include the font too large on every page). When I try to change the titles of the footers in the master, nothing happens. When I try to add a new master layout, the footer - even after re-saving the files - see non. What am I doing wrong? Please help me to sort out the problem.
