At the end got it working, In order to get rid off the error we need to activate the Excel services web service application proxy in web application service connections.

In case the above mentioned proxy is not available under the service connections, go ahead and create one. Need some help, its right here !!

EXcel Web Access - web part Error
I've been using the Kindle reader app on my iPhone and it was working as advertised for a while. However, yesterday for no apparent reason it has stopped being able to download books. I bought a book, went to my list of books in the Kindle app, and tapped the "download" control. The message reads "Downloading 0.0%" and just stays there. I tried downloading another recent purchase. Same deal. I tried restarting the Kindle app, and then the iPhone, but that didn't help. I tried going onto the Amazon and "sending" the books to my iPhone with no result. I made sure the iPhone is connected to my home wi-fi network.

Has anyone else seen this problem? Know of a solution?
