Force close the application, log back in and WAIT. If you get a couple of ads and then they disappear again repeat advice. If you get the ad button but pressing it does nothing, repeat advice above.

If this resolves your problem then I think you've been put in an ad naughty box. This has happened to me a couple of times and just watching five ads per day eventually resolves the problem. I try to keep my ad watching to a minimum and only use them when I need them.
