Im trying to download my high schools podcasts, and when I go to advanced, subscribe, the subscribe button is grey and i cant click it. I do have an account that has a credit card number and all the necessary stuff, so thats not it.

Help please?
Perhaps you already ARE subscribed?

Try downloading one first....then under options click "subscribe"
