A prior post suggested contacting Eovia about getting the physics stuff to work if you are a C1.1 user with a C1.0 CD.
Their response was as follows:

Truly, I do not know the exact procedure but I bet it wouldn't be too difficult to figure out. With consideration given to business etiquette and/or political correctness, it probably wouldn't be very prudent of us to make such information readily available anyway.

In any case, we should get license for use very soon.
