[Limdep Nlogit List] error in multinomial probit

[Branka Valcic]

Hi,

Can somebody, please, tell me why I would get an error message while 
running a multinomial probit saying "Division by Zero...."? In other 
words, could you suggest to me what I should be checking in my model 
that could be causing this error?

Thanks so much!
