iTunes U greyed out?

[maus]

For the past week or so, I've noticed that many of the iTunes U downloads have been greyed out, making it impossible to select/download them. Has anyone else been experiencing this? Is there a solution?

You need to make sure that "Podcast" is enabled in iTunes and also in the parental section make sure "Podcast" isn't disabled.
I had this problem and it drove me crazy until I stumbled across the solution. Hope this info helps. Cheers Gav
