Hey @yoshi2000

Had the same problem. In my case it was this piece of code in a few template files for checkout (shipping.phtml, billing.phtml etc) in my theme 

<?php if($this->getLayout()->checkVersion('1.9.3.x') 
			and !$this->getLayout()->checkVersion('1.9.3.0') 
			and !$this->getLayout()->checkVersion('1.9.3.1') 
			and !$this->getLayout()->checkVersion('1.9.3.2')){
	?>

Changed the top 1.9.3.x to 1.9.4.x and all worked. Just do a contents search for "1.9.3" in your theme files under \app\design\frontend\YOUR_THEME.
