Error loading project : Version string portion was too short or too long

I am trying to load my project in Xamarin Studio and I am getting the error, "Could not load solution: Version string portion was too short or too long." (See attached screenshot)

I can load and work with the solution in Visual Studio 2013 just fine. However, I prefer to work in Xamarin Studio when I can. Not being able to load the project is concerning me.
