can't run simulate on a part previously analyzed in Ansys

I’m dead in the water until this is fixed.

I got a part from our anayst that was previously analyzed in ANSYS workbench.   I’ve gotten these many times before, and used Simulate to analyze my modifications.   The file I get is a Creo part; nothing special about it.

When I bring the part into Simulate, I can add material, loads, and constraints as I normally do.

But the mesh icons are different from typical, there is no AutoGem, and when I go to do the analysis I set up, I get options that are different (ANSYS, NASTRAN, or neutral file).  The analysis doesn’t run, and the mesh created doesn’t save with the model.

I can't find anything in the model setup that says: "only allow this part to be run in ansys or nastran".  Anybody know what the heck is going on?
