I get that on New Romulus. Their tech support has never helped at all. I can only guess they do not support AMD/ATI cards, because every person I ask that has that error has one of those cards. I have not been able to play on New Romulus for almost a year because I crash within 15 seconds when I get there.
DAY 5: Finally the problem is solved, no more "server not responding"!
