as you see, you connect to the ecsro server.
the numbers you got, are probably the onbes for mysro.
if you plan to play on ecsro, just click the upper link in your panel on mysro.cn
soo.. instead of klicking the red one like here in the image:
just klick the link above it (the blue one).
and then try to log in with the data you get from there.
if you really want to connect to ECSRO, and everything is ok, then the error may be the server that's full...
