Dashboard Movies Widget suddenly not working

The built-in Movies widget from Apple (that shows movie posters as a slide show on one side and theaters/times on the other side) has suddenly stopped working. I tried to quit and reopen from Dashboard, move the widget out of the main library's widget folder, reinstalling by double clicking on it, removing preferences, deleting system cache, history, repairing permissions, copying the widget from another computer: nothing worked.

The rounded rectangular window simply shows "No movie data available" and clicking on it does not make it flip as it normally should. Therefore, it is just sitting there on the dashboard, not showing anything other than the sentence above, and cannot be customized. I can open several of these Movies widgets simultaneously and none works nor flips.

I cannot think of anything that might have made it stop working (my internet is OK, not a firewall issue). Any suggestion would be appreciated.

Thanks.
