+I tried Sandaddict26's solution and so far it seems to have worked! I followed the instructions, which made it strangely open up iTunes U page in the Store; however not letting me go to anything else in the store. I then turned off the Parental controls of the iTunes Store, and it's gone back to normal! I didn't try your idea dirtrider6591 because it was going to take more time than Sandaddicts, but thank you for putting up your solution. :)+
I second this! This worked perfectly for me, I did it exactly like this. Thanks to both pippy1992 and Sandaddict26 for the help:)
I tried dirtrider6591's solution first, but strangely, that did not work for me. I didn't try to restart my computer though.. I decided to try out the other option instead, since it seemed easier, and that worked! Anyway.. I would just give a warning if you try to re-authorize the computer, I think you lose one of the authorizations, and you only have 5! At least I did, and now I only have 1 left! Just a little warning if you try this solution..
