This error started for me today. Wondering if anyone else is having the same issue.

Everything is fine all the way through the character selection screen, then it gets stuck on the "downloading data" black loading screen. Then the wonderful error box appears.

I hope SE fixes this issue quickly. It takes a long time to get to the point of logging in, just to find it malfunctioning.

I've scoured the internet for similar issues, but I can say with certainty that it's not windows firewall (mine is turned off) and it's not issues with the router (I don't have one). Anyone else with the same issue?
