Assuming that you have fixed your problem with -nlsur-, 
which you realy should because it makes no sense to try 
to interpret a model that has this problem, and that you 
still have a problem with -nlcom-, then you can try to 
rescale your parameters, such that the parameters aren't
too large or too small. You are squaring them, so very
small number become very very small and very large numbers
become very very large, which may cause problems.
