I had a flaw in the theme that I was using that prevented the WP in Post Ads from showing. Even though it was a Sunday I posted a request for help on the Forum and MyThemeShop added the missing code needed to get the ads to show.
The ads look great particularly because I used a nice font and used white on blue background.
I found that it worked better to change the type face to white from the wordpress editor than from the WP in Post Ads Editor, although I had no problem setting the background color in WP in Post Ads
