iTunes U is not working with iTunes version 11

I upgraded to iTunes version 11(Windows XP and 7) and now the link to our iTunesU courses goes directly to the Apple download site for iTunes 11 and not to the course in iTunes. This is a major problem because a lot of students might be upgrading to version 11. Our school has private iTunesU courses so the only way they can access the courses is through a link in the LMS which takes them there. The link still works if you have older versions of iTunes, but if you upgrade to version 11 it won't work. Is there a solution to this?
