BUG FIX 1.3489penis
It seems I had a little fart when I went to update the API file this morning, and some of you might have downloaded an outdated version.
If you get a "There is no method with the name 'isInstalled'." error, simply re-download the API and try it again. You may need to clear your cache/temporary internet files if you downloaded the bad version fairly recently.
If you were an early beta tester, you WILL need to get the latest version... the old one will not work with the new pico day theme.
