Visual Studio Crashes When Opening Project

Question

my project has stopped loading - Visual Studio 2013 just crashes and I'm really worried I wont be able to continue my work on the project solution. I've found this error in Visual Studio's Activity Log, but I don't really know what it means, can anyone help?

Visual Studio does open on it's own, but I cant run the project solution I've been working on.

Try clearing the Visual Studio component model cache.
