Package source named "NuGet" is invalid or unavailable

I installed Nuget 1.2 yesterday, and today, when I tried to install the Entity Framework package, I ran into the following problem in the package manager console:

PM> install-package entityframework
Install-Package: a package source named "official NuGet package source [https://go.microsoft.com/fwlink/?LinkID=206669]" is either invalid or unavailable and therefore currently not available.
On line: 1 char: 16
+ install-package <<<entityframework
    + CategoryInfo: NotSpecified: (:) [Install-Package], InvalidOperationException
    + FullyQualifiedErrorId: NuGetCmdletUnhandledException, NuGet.PowerShell.Commands.InstallPackageCommandand

I can catch up with the Internet, and I don’t think that something prevents Visual Studio from accessing the Internet.

In fact, there was something that prevented Visual Studio from accessing the Internet. It seems that VS had problems with my proxy.
So I used the solution presented in here , and now everything is working fine.

The same problem occurred with my setup. However, I found that VS 2010 uses proxy settings from Internet Explorer. I deleted the proxy settings from IE and successfully connected.
