Hello Jeff,
There have been several reports about this problem in this newsgroup. I
have not personally seen it. I use both Project 2007 Professional and
Project 2003 Professional and can open files created in 2007 and saved
as 2003 without problem.
I could reproduce problems cited when the project files were password
protected, but just "regular" project files without passwords seem to
work fine.
In a quick google groups search of the project newsgroups, I don't see
any resolutions posted. I have also checked the connect site
http://connect.microsoft.com/feedback/SearchResults.aspx?SearchQuery=2003&SiteID=235
and have not seen any reports of this error nor obviously any fixes.
Sorry I don't have any better answers for you other than to say it has
been reported before. Sorry.
I hope this helps. Let us know how you get along.
