short question

I'm trying to replicate a paper but with data for a different country. I tried to simulate the model first, with the parameter estimates given in the paper, to check whether the model was correctly written. Then i try to estimate it... and i get that with these initial values (the same as in the simulation) it's not possible to compute the likelihood. Is that possible, or did I do some mistake in writing my code? I checked many times, but i can't find the problem.
