Can't get a link from In Post Ads to work

I’ve installed In Post Ads on for use at the bottom of posts and pages. The create-ad page and the ad shows up fine, but I have two questions:

1) Why doesn’t the link that I put in on the upper right corner of the create-ad page work?

2) Is there a way to configure the shape of an ad via In Post, e.g. I’d like to run a more vertical one alongside the post rather than at the bottom or midway through the post. If not, is there another WPMU DEV (or other) plugin that could do this?
