Make sure that in WoW/WTF/Config.wtf the realmlist is set as:
SET realmlist "192.223.25.140:3725"
If there are problems with client files, then you can refer to these two screenshots, what show how data and locale structure should look:
<div class='spoiler_toggle'>Spoiler: click to toggle</div><div class="spoiler" style="display:none;">
