I just upgraded to 3D Via version V6R2013. I was forced to do this because I was no longer able to open my customers models. I was getting an error which said that they had been saved in a later version of Solid Works. Unfortunatley I am still getting the same error even with 2013 loaded, but I have noticed that when I go to open the model the indication is that the 2011 importer is still being used. Is there a more current importer?
