[Plugin: WordPress.com Stats] Stats not showing in Dashboard

Strange behaviour… the stats have stopped showing in the dashboard…. the full view works OK, but the “excerpt” is empty. And this is in one computer, when logging in the same user from another computer, it seems OK. Have tried to activate/deactivate the plugin, have removed/added the “Stats” from the dashboard, have removed/reinstalled the plugin… with the same result. No stats in the dashboard.

Any advice?
