I liked this UI also, but it hasn't been updated for quite a few patchs, and isn't going to work for you without some serious updating on your own. Since I am too lazy to do that myself, I just looked for a more recent UI, and found this one:

Been using this one for almost a month now and am a big fan, give it a shot
edit. The thing with that one is the pet window is replaced by a timer...which for most druids isn't good...just copy the default pet window file into the installed folder and you will get a normal pet window, or you could search out a cool pet window...but again, the laziness factor
