Family.Show has stopped working


"A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."
I downloaded family show v2 and started developing our family tree last night. Today, I tried to continue expanding the tree, but the tree view is missing. I can see all of the family members list and the expanded view.
When I select any of the family members to try and bring out the tree view, I get the above error.
I am able to view the tree for the sample windsor.family.
Any ideas?
