when I assign materials Archicad freezes

[Anonymous]

I have duplicated some of the materils from material list to be project specific. Whenever I try to assign materials Archicad starts to freeze. I have removed the preference folder and reinstalled Archicad. The problem keeps coming back. Can anyone help please!
