Did you take a look at the tutorials?

They clearly show how to customise your popups!
There is a lot of software out there that has a free version that you can upgrade for more functionality.
Clearly you did not try to setup the Lite version as it’s full functional if all you want is to create a single popup that integrates with Aweber, iContact, GetResponse, MailChimp and Constant Contact.
If you where having trouble setting it up after you watched the video tutorials then all you need to do was ask and we would have helped you.
Yes there is a single banner on the lite version and yes if you click any feature marked [pro] you will be told that it is a feature of the pro version.
Popup1 is fully functional. If you want 4 more popups or 3 inline optins or you want to add youtube, vimeo or self hosted videos then yes you will need to upgrade. But if you want 1 popup and want to build a list with on capturing the email address and add what ever images you want the all you need is the FREE lite version.
