I have a mod file that successfully performs an estimation of my DSGE model in Dynare 4.1.3. The same mod file fails in 4.2.0. Here is the message I get:

Error in computing likelihood for initial parameter values

??? Error using ==> print_info at 39

Blanchard Kahn conditions are not satisfied: no stable equilibrium

Error in ==> initial_estimation_checks at 101

Has something changed in 4.2.0? Can anyone give me some ideas about how I might try to fix this?

Thank you.
