Which one did u rpelace? I guess its gtk2-aqd or something? then you need to find the package named exactly but without aqd. I guess the removal instructions shoudl also be there on the site where u downloaded this.
Edit: in the other thread i saw the screenshot of your install. Everything is fine. the problem is that you prolly haf the macmenu applet badly placed.
first from the top panel, remove the Menu Bar and install put the applet Main menu. Then beside it put the Mac menu applet and move those textedit, terminal etc. shortcuts to the right. Also shift the Window list applet to the bottm panel and everything should be fine
