Like I said, the port you see in the GUI is the ControlPort. You're not supposed to change it. If you followed my instructions, the SocksPort has been changed to 9050. You say that it's asking for a password. So when you click "Get Mail", does it say "connecting" in the status bar, followed by "connected", and then it asks for you password? If that's case, you are connected, but your username and/or password are wrong.
