Wordpress Plugin Widget Ad Plugg Version 1.2.26

Sorry, this question slipped through the cracks and this answer is really late, hopefully you got everything working.  I wanted to respond to help anyone who comes across it:

Where do I place the Machine Name Code in the Plugin on Wordpress?

When you expand the AdPlugg Widget, there is a field called Zone.  Place the Zone Machine Name into that field.

Where do I place the Tag code?

The AdPlugg Widget is used to place the Ad Tag into your site.  So if you are using the Widget, you don't need to do anything else. 

It should be noted that you can place the Ad Tag using the AdPlugg Widget, but if you wanted, you could alternatively paste the Ad Tag into a Text Widget, Post, Page, or directly into one of your theme files.

What information should go in the Title text box on the Wordpress plugin?

This is up to you, you can leave it blank or some sites like to put something such as "Sponsors", "Advertisement", etc.

A clear step by step set of instructions would be helpful - identifying and clarifying exactly where every piece of code or information goes.
