Mobile air Mouse "Installed" but "Not Installed"

In maintenance - install extras, mobile air mouse is showed as “installed.” Under maintenance - settings, mobile air mouse is showed as “not installed.” Any ideas as how to resolve this?

Thanks.

You may try removing it and reinstalling again. Any ‘extras’ can be removed through the Install Extras menu. Just highlight the item to be removed, press the right arrow (>>) and follow the prompts.

Ok. Easy enough and it works.

Thanks
