geopak ss2 corridor modeler with windows 10

I'm using Geopak ss2 with corridor modeler with windows 10.  (Yes, I know geopak ss2 wasn't certified for this windows version.)

Notice that I can import gpk geometry to create corridors, point controls etc...  But, if my gpk geometry changes, when I update the alg file all my roadway designer geometry stops working.   It appears that the alg file loses the guid that associates the geometry to the roadway designer.

Anyone see this issue and have a solution?   wonder if I need to roll back to windows 7.
