I am trying to figure out if this is a problem on my computer or an iTunes site issue. I keep getting an error every time I try to download anything purchased or free from iTunes. Here is the error I get when I click on the "I agree to the purchase agreement" from the store: Could not purchase "xxxxxx". An unknown error occurred (5002). There was an error in the iTunes Store. Please try again later. This has been happening all day since I did the software update for Leopard and the iTunes version upgrade. I have checked that my computer is authorized, it is, and that I have my permissions correct in my itunes folder, they are. Any help is greatly appreciated, thank you.
