[Plugin: Magic Action Box Pro] Having trouble with Magic Action Box

I downloaded the free version of Magic Action Box to check it out. I played around with all the customization like changing colors, adding text, added a picture, and copied a link to my email sign up form from Constant Contact. But when I update or preview the page it never shows up after the post where I added it.

I am growing frustrated. Seems like a great tool and I’d consider buying the paid version but if the free version does not work for me I begin losing confidence in it. Already sunk a lot of time into it tonight.

Your input would be appreciated.
