Taking a closer look, the close button is missing from the broker window as well as the fonts. All that information is stored in the _ProfitUI_Styles.xml file.
When you updated the market window, did you copy over the new _ProfitUI_Styles.xml ?
Try and reinstall the market window again and overide all the files (except the eq2ui_custom.xml one)
