 1. Check if project will open successfully from another workstation:

• If yes, verify data is okay, then save the project back to Clarity. 
• This will allow all users to be able to open the project

OR

  2. If you have a backup copy saved on the workstation with the current data, try saving that copy back to PPM and verify if the project then opens successfully.
