Error message:the document '*projects.mpp' caused a serious error
error message when opening the Microsoft Project program : "The document 'projects.mpp' caused a serious error the last time it was opened. Would you like to continue opening it?" Files open properly and work fine, but everytime I open the program, this
message comes up with the last file that was used.

I also often get this. It is caused by opening a file that was created in a different version of Project, changing it and then saving. You could try Save As... and give it a new name - sometime works for me. You could also try opening a new projrct and
inserting the project into it, then Save As...
