BBCSO Discover not working GarageBand after update

Hello, my BBCSO Discover is not working GarageBand after the recent update. A few days ago I used the plug-in, then saw that an update was available so I did it. Now when I try to load it GarageBand says "The Audio Unit “BBC Symphon” could not be loaded for your project, and may need to be updated. Contact the manufacturer for an updated version or further assistance." Does anybody have any idea what I could do to fix this?
