The read_message method works and passes tests. Make sure you're using the latest version.
If you are using the latest version, what URL shows when you log into your account using a web browser and go to read a message in it? Does it start with "messaging.myspace.com" or with "mail.myspace.com"? (that's an either/or question, not a yes/no question).
If it starts with the latter, this might be the problem as your account is on Myspace's old mail servers still.
If you can do a "get source" and paste the page's code here we might be able to update the read_message method to handle both forms. (be sure to use the "code" tag as described in the forum's Posting Rules that should appear underneath this message in the forum
