Sory for the delay in answering. I got distracted by some things.
WHen your adsense is working, it should say Active in the affiliate settings page.
To see that page, log into hubpages. Click EArnings and click Affiliate settings.
In the page it should say something like this:
Program Affiliate Code Status Reports
configure Google AdSense ca-pub-16650359215102156 Active
Do you understand now?
