This may be more a T4MVC thing than a NuGet thing, but here goes.

I'm running VS 2010 RTM, NuGet 1.0.10128.89, and MVC 3 RC2.  When I try to install T4MVC NuGet, I receive the error message:

Install-Package : Failed to download package correctly. The contents of the package could not be verified. 
At line:1 char:16
+ install-package <<<<  T4MVC
    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidDataException
    + FullyQualifiedErrorId : NuGet.VisualStudio.Cmdlets.InstallPackageCmdlet

I have installed ELMAH into the same project, without problem.

Any ideas what I'm doing wrong, will help.

There was an issue on the server, which should be fixed now.  Please restart VS and clear your IE cache if you still see issues.

Perfect!  Thank you. Problem Solved.

I am getting this same error really quite frequently - in particular (but not exclusively) with:

PM> Install-Package SQLCE.EntityFramework

The work-arounds mentioned above do not always work.

An additional work-around I attempted is to copy the 'packages' folder (found in in the solution root folder of a previous solution)

To clarify - where the above command has previously succeeded in downloading the package (within some other solution) I find that I can copy the packages folder and the command then works (presumably because it no longer needs to do the download but, only the install bit).

However - even the above workaround does not always work (it still did not work for 'Install-Package MvcScaffold' until I restarted VS2010).

This is quite frustrating and I hope it can be resolved before RTM.
