When I do a Google search for "National Instruments", Google pops up an Icon on the Menu Bar (third from the right edge) that if I hover the mouse over it, says "My Account", and lets me log in to NI's Web Site. Through this, you can get to Support, which can get you to the NI Learning Center. [Note -- the organization of NI Learning is a little clunky and "messy" to navigate]. You should be able to find Core 2 there, and see if your License allows you access to it.
