This is a brief procedure assuming you have a .mechdb that is intact.


  Sometimes  re-importing the mechdb/mechdat can resolve these issues.  


  In your project folder, there should be a SYS.mechdb file for each Analysis object that was on the schematic.


  - Make a copy of SYS.mechdb to another folder,

 -  Rename the copy to SYS.mechdat


Once you have copied these out, create a new Project..

 From Windows Explorer, drag the .mechdat files into the Schematic

Save the project to a new name when you are done.


Let me know if this gets you going.
