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.

Hi lake country,

Welcome to this Microsoft Project forum:)

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...

Hope this helps - please let us know how you get on :)
