My experience with -nl- is that often it needs user specified
starting values in order to achieve reasonable convergence.
But when I specified these starting values, it tends to work
quite well. An example of how to specify starting values is
given in this post (and ofcourse in the documentation of -nl-):

Hope this helps,
