Composites-specific Failure Criteria not available

I am using Simulation Premium 2010 and am attempting to run an analysis on a simple composite panel to get a feel for it. I have defined my composite panel with multiple plies of the same material. The study runs fine but when I attempt to create a FOS plot, the composite-specific failure criteria (i.e. Tsai-Wu, Tsai-Hill, etc...) are not available. I tried defining my ply material as both an isotropic material and orthotropic. Obviously, I'm dealing with a fiberglass composite panel so my UD plies of have orthotropic properties. Any ideas?
