Hey! As long as you remember the Playonline ID and your playonline password you don't need member password to log in. If you can't get past the member password, try reinstalling the game completely to erase it.

You could try logging in as a guest as well, using your Playonline ID and password.

Depending on whether or not you have linked your SE account to your Playonline account you may have to enter your SE ID and password as well.

Hope this helps!
