[phenixbb] How to reload a project into the gui

Hi, during a phenix refinement the gui froze and I had to kill the process. After restarting the gui the project I was working with was disappeared - all other projects are still there. Is there a way to reload the project into the gui? All files including the project folder still exists but are somehow not recognized by the gui. I'm using dev-249 64bit. Greetings Dirk
