Some iTunes users locked out of accounts, downloads

A number of iTunes users, including at least one iLounge editor, are experiencing difficulties logging into, and downloading items from, the iTunes Store. Two separate error codes, error -4 and error 5002, have been associated with the issue, and may be a sign that users have been locked out of their iTunes accounts. Several users on Apple’s discussion boards believed that the problem was related to a change to the country in which they were browsing listings, however, it appears that this is not the only way to bring about the error, which results in an inability to access one’s account with the previously chosen password. Attempts to reset the iTunes account password, and/or toggling the iTunes Store’s One-Click/Shopping Card settings under Preferences>Store, may fix the problem.
