  Previously, when I use journal recording, maybe I didn't stop it. after I close workbench, I lost all the files. but the cells still in the workbench but with a black cross. I can't delete the cell.

  I can redo my work. What I tried to do was to save my file as a copy. it seemed I didn't succeed and lost newly added cells. the new created workbench file has nothing in it. old version file has newly created cells but can't access.
