Sometimes the saved screen settings get corrupt and you will not see any data in most of the graphs. Usually when this happens you will see zeros next to all the graphs.
To resolve this issue open the Freeze-Framer and click the Options (In Freeze-Framer 1, "Set or change optional settings") button from the main screen. When the Options window comes up, see if the option Last Saved is selected. If it is then change it to Default, if Default is already selected then try changing the Saved Automatically option and then click Ok. Exit the Freeze-Framer and then open it back up and run a test session. You should now see data in the graphs.
