I've looked all throughout the MacRumors: Forums and even through the Apple.com Discussion Boards and have found very limited info on my problem, so I'm deciding to post. Here's my issue: I was in iTunes and clicked "Write a Review" for a song. The dialogue box popped up asking for Account Name (which was already entered) and a Password. I entered my Password and clicked "Sign In". Box goes away...A couple of seconds go by and the dialogue box pops up again. Enter my Pword in again and the box goes away and comes back. Over and over I did this, until finally giving up. Oh...and I have no problem being able to log in to download Songs, Apps, etc. So it seems like only the Review Writing is effected? When on the Apple.com Discussion Boards, I found mention of this issue, and the solutions were, "Restart your Computer", "Restart iTunes", "Log out and then Log Back In", etc. I tried all that, and had no luck. I thought I would try to post a reply on the Boards, but I needed to Activate my Apple Account to be able to post to the Boards. Went through all the steps, and ran into a similar issue after clicking the "Submit" button after accepting the Terms & Conditions. I sent an email to Apple...They received it, but I have had no response yet. I thought I would post on here, just in case someone has already heard about this and has a solution. Thanks!
