I installed the plugin but cannot figure out how to implement the code.
What exactly is the "code block" and why isn't the actual line of code described in your installation guide? Couldn't you specify which exact parts of the code to remove/edit instead of just saying the code block of a fraction of that code?
On WordPress 3.4.2, I do not see a loop.php, so this is obviously a different file to edit. Can you specify what the file and code is that I need to edit for the twentyeleven theme on WP 3.4.2?
