By looking at the program, I think I have found the problem. When you do the selection of the vertices on the head of the character, Are you sure you always use the good character name. When you select a character in the list, in the hair tab, many vertices, defined by a number in the HRV file, are defined as selected on the head of the character. If the character is not the right one, some vertices can have an indice higher than the number of vertices in the character. I should have done this test but it don't exist in the program. This could explain the access violation you have . I will correct this forgetting in the next version.

Could you make a test with Genesis 3 character and Import a hair using the "Genesis 3 DAZ" in the listbox.
