WOTLK problem

Ok hi guys. well thing is i cant login using my warmane nick(username), i can only log in using my email but that opens patch thing and brings me to official blizz servers. Im using old wotlk game client world of warcrat 3.3.5a (no install). Thx in advance

where did you get the Wotlk Client? you need to change the realmist, this is the correct one to play here:
set realmlist logon.warmane.com
