TF31003 tfs Error in Visual Studio 2010 and Visual Studio 2012

I am working with the Visual Studio LightSwitch 2010 and 2012 htmlclient version. Suddenly I got an error while connecting to tfs. The error is like as

TF31003: Either you have not entered the necessary credentials or your user account does not have permission to connect to the Team Foundation Server at https://***.visualstudio.com/. Ask your server administrator to add the appropriate permissions to your account

Solution:

After a long search, I got a solution of this error. That there is some cookies problem with internet explorer. 

Open internet explorer and press buttons Ctrl + Shift + Delete



after deleting all the cookies try to connect the tfs. I am sure that this time you will connect to the tfs and no error will occur.
