''you have been disconnected from server''

hi..

but i can enter character in other realms like blackrock. lordearon..
thats weird.

i tried delete cash no work.
all of my addons is from trusted site.
i tried changing DNS but no work too.. run as administrator.. winXp3..
my ping is stable always 50-60

and no one using my account with me.

my realmlist is like this ---- ''set realmlist logon.warmane.com''
