Testplating / Optimization Stall (05/13)

Hi All:

I am testplating a zoom lens.   As part of the process after optimization, I  would “Fix” both infinite radius surfaces, as well as the base radius of any a spheres.    In this case the error function is about  ~ERF=0.4966.   

However,  when starting the testplating operation, note that the dialogue box recognizes the prior error function of ~ 0.496,  but then estimates an ERF of ~9 Billion, and then Zemax stalls completely

The merit function going to 9E9 is an indication of an error condition, but I don’t know what the error is. Neither of the attachments seems useful to me, could you post the file? -Mark
