my computer can't make nurbs.
 

i'm desperate. i can't make shapes with nurbs. this is what the little window on the bottom right corner says when i try to make a nurbs sphere: "Error: MakeNurbsSphere1 (Make Nurb Sphere Node): Failed to compute the result."
and all the values in the "NURBS surface history" scroll-down window are zero, and i can't change them.
if it makes any difference, this is on a mac g5 and (i think) it's on the jaguar operating system. and i can make all the nurbs i want on the other g5 with the same program.
i can make any shape using the polygon primitives thing.
thanks, if you can help.

Try unintalling then reinstalling Maya.
