Hi and welcome.
If you open CPF and go to security/tasks and click on scan for known applications, you should be able to run MSN. I don’t have any problems with that.
You should only use one firewall, otherwise there can be some conflicts.
Are you behind a router? In that case you need to create a trusted zone.
Do you have default rules?
You can check in Application monitor if you by misstake have a block on MSN.
