I've been trying to connect for hours now and all I get is, after slecting Role Playing Character:

--------------------
Guild Wars was unable to complete the operation.
Please try again in a few minutes. (Err=10)
--------------------

I purchased the game online through PlayNC.com TCP on port 6112 is opened.

Since there's no official forums and no statement from GuildWars on their site, I have no idea if this is a known problem, just too many people trying to connect today, overloaded servers, an account problem, a network problem or what. Would be nice to know what needs to be done to play.
