EC Error

I admit it's been three months since the last time I checked on my EC Drops Inbox and some of the paid ads were also left unattended. I checked on my EC account two days ago, did some EC drops as well as approved some paid ads but when I checked on my site, the paid ads won't display. It always gives me this notification whenever I logged in and have my site checked:

Our automatic widget scanner can't find any sign of the Entrecard widget on your website. To put the widget on, go to Get Code and put your choice of widget in your blog sidebar. Check my page now.

What could have been the prob? Am worried about the people who paid for their ads and I wasn't able to post it on my page or rather display. To all, am really sorry. I will try my best to really find the solution for this. Please bear with me.
