• Check the Projection Start Year in the Status Bar. You may have set a Projection Start Year to a year greater than the year allowed by the program.
  
  MasterPlan does not let you set a Projection Start Year that is greater than the current calendar year. However, if you have moved the database from one computer to another, it is possible that you have moved the database to a computer that is running an older version of MasterPlan.
  
  To correct: Make sure that all your computers have the most recent version of MasterPlan on them.
