Just recently, I started using mudfish again to make my Guild Wars 2 have a stable connection. I am able to login successfully, however after selecting my character, the game is stuck at the loading screen always. This did not happen before.
Is it even same with different mudfish node? And did you try to change Connection Protocols to another?
Thank you! Apparently changing the connection protocol worked!
Cool! 
I hope now everything goes well with mudfish. Please let me know if there are any other problems.
