It doesn't look like that has been updated since the last patch.
open your eq2ui.xml file in a text editor and add the following lines anywhere above the last line:
Code:
<include>eq2ui_commonelements.xml</include>
<include>eq2ui_textstyles.xml</include>
<include>eq2ui_shadowstylesnew.xml</include>
<include>eq2ui_specialelements.xml</include>
<include>eq2ui_arenachampions.xml</include>
And that should fix your problem.
