John is right about the shortcut; and you can always create another shortcut. BUT ... it also sounds like it's time for Utilities/Project/Check/Repair. This optimizes the project and library files and if the places are not found, the place is restored with the name Missing Place no. nn, giving you the option to find what place is missing and correct it.
You might also want to do the fixme.bat, too. That never hurts.
