I moved the Respondus Projects folder. Now I get an error message when I open or create new files.

The location of the Respondus Projects folder (which stores your data files and other program settings) is selected during the installation of Respondus 4. The default location is the user's "My Documents" folder. If the location of this folder is changed after the installation of Respondus 4, go to File > Preferences > General and then "Update" the location of the Respondus Projects folder.
