Spark messenger question

Hello so I just got spark messenger and I am trying to conncect to facebook with it and when I try it says unable to register with gateway whatever that means and it says the password you registered with is incorrect how do I get it to work?

Thank you for any replies.

Do you mean that you press Facebook icon on Spark’s toolbar and then enter your facebook’s login information? Then you are using Kraken XMPP gateway plugin on your Openfire server (the server Spark initially logs into). That plugin is very old, so most probably something has changed on Facebook’s end and this plugin doesn’t support it anymore (or maybe Facebook just blocked any other clients other than their own).
