[Plugin: Advertising Manager] No Adsense Ads

I have downloaded and installed Advertising Manager, latest version. I cannot get it to display adsense ads, and there is no space for the ad. When I click View Source, the code is in the source. I am using the Studio Press Genesis Child Lifestyle theme. I have spent the better part of 2 days trying to get this to work.

I just found out that my adsense ads are showing on my laptop but not on my desktop. I guess I have them blocked somewhere.
