The answer is almost certain to be you did not include the command to load the Statistics`NonlinearFit` package in the notebook you saved or did not execute the command to load the package before evaluating the cell with the call to NonlinearFit. Look to see that you have one of the following in the saved notebook

Needs["Statistics`NonlinearFit`]
<<Statistics`NonlinearFit`

When you know you are going to be working with a given package it is a good idea to have the Needs or Get function be the first executablble cell in the notebook

BTW, there is very little advantage to using NonlinearFit over the built in function FindFit.
