I am using Bing Search on one of my mp site, and it is still working, but on 8/1/2012 they say they are transitioning to the newer Azure bases API keys,

So i opened the account and activated key for the free level search API. and changed my api code to the new one.

boom error page:

Looks like it is affecting the http://www.mojoportal.com/BingSearch.aspx search page too:

my log4net:

I will start debugging local now to see why the old key works and the new one does not.

Thanks Joe, I am in the process in integrating the dev branch into my local.

But just want to point out as well, this site ( http://www.mojoportal.com/BingSearch.aspx)  producing an error.
