Error: Invalid resource directory name: "res packages.config"

I've searched, and searched, and searched... and I cannot find the answer to this problem I am having.

I got a new laptop (Window 8 installed) and installed Visual Studio 2013 update 4. Then I installed Xamarin Studio. I created a Xamarin.Forms project and keep getting this error:

Error 3 Invalid resource directory name: "res packages.config". C:\Users\DefaultUser\Documents\Visual Studio 2013\Projects\NewProject\NewProject\NewProject.Droid\aapt.exe NewProject.Droid

I tried on both Visual Studio AND Xamarin Studio. I did not change any code, go on Nuget and update anything... nothing was done. And I get this error.

Anyone know of a solution or what I might do to fix this?
