Do you have the "Cards" component and is it referenced in your project? Also, I run into all the time references within that component that are not valid on my machine. You could open the Cards project and expand the references tab to see if any of the references are not valid. The ones that are not can probably be removed and re-added back on your machine and then rebuild that project.
