HELP! "Font Plugin" not working properly

I have been using the “font plugin” created by Pawe? Misiurski for the last week and everything was great! Until today! When I click on font settings link an error pops up from the browser (both firefox and chrome) that states ‘An error has occurred and your plugin is not working. If you are working on a local server, make sure you have an internet connection.

I have called hostgator but they advised the issue is not with them.

If you have any advice, I am here! Thanks
