You should now see something about saving data locally. It's probably set to enabled already, but even if it is:

tick ENABLE
Now hit the close button.

For some reason, this setting sometimes messes up, and resetting it through this trick tends to work.

I found a better way. Go to Control Panel, and check Flash settings. Add nutaku's site to the white list and/or do a global cache. It's not that the settings in the browser control is messed up, but your default WINDOWS configuration is overwriting your browser level settings.
