Have you tried re-downloading the tool? If that doesn't work then make sure all your drivers are installed, and make sure fastboot it working! If none of that works then try it on a different computer!
So I never installed clockwork so mine updated just fine, but I have the US version. The kit-kat update also un-rooted my tablet. I would try re-flashing the stock recovery and then try to install the update that way!
I've had similar problems, but at this point you don't really need a custom recovery considering there are no custom Roms or kernals avaliable. I'm just gonna keep stock recovery so I can get the kit Kat update when it comes out!
My homescreen
Using Google expierence launcher! With gravity box to make the status bar and navigation bar clear, and also to make status bar icons white. I also use HD widgets. Also have wallpaper changer that changes my wallpaper ever hour or so!!
Looking forward to seeing everyone's screenshots!
