Hello all,

I am currently attempting to fit a random-coefficient Poisson regression
model in GLLAMM using the estimates from the previously fitted
random-intercept model and I get the error message of... 


(error occurred in ML computation)
(use trace option and check correctness of initial model)


I ran the trace option and get a slightly different Liklihood {-681.3
compared to the previous -683.4).  I am exactly neither sure regarding
the meaning of the error message nor how to use the information from the
"trace" check.

Thanks in advance for your time and attention to this matter.
