Guild Wars 2

I think a “Ninja” specialization is a good option to the game. Stealth and quickly hits.

Hello, everyone.
I’m trying to log-in the laucher, but when I do this, this error appears: “Guild wars 2 has encountered an error”
The error code is: 42:0:9001:4409
I ever played this with my firewall enable. I really don’t know what is it.
I’ll attach a screenshot with the topic.

Thanks for your time and help.
