I, too am getting this problem. In 2007 I installed the trial version of 2007
to evaluate whether we needed to upgrade to 2007 or keep using Project 2002.
I only ran it a few times, then decided to retain 2002. A few days ago I
accidentally launched 2007, then shut it down. Now, whenever I go to save any
file in Project 2002 I get this error. This even happens with brand new
project files, not just previously-created ones.
