Ok in trying to get this to work I uninstalled everything and reinstalled. When I tried to do the compare on a .page file I got the following errors (copied from the attached [attachment=59:ActivityLog.xml]log file). I hope this helps. I can do a compare other files (.cls files and triggers.) but fails on the page files.
Thanks.
