Simulation but no estimation

Hi professor
I have a problem with my DSGE code and i wish that you help me.
when i simulate my model, it seems that there is no problem and everything ok!! I mean that model give me impulse response figures and other ones. But when i want to estimate the model. it give a following error:
Error using print_info (line 42)
Blanchard Kahn conditions are not satisfied: no stable
equilibrium
Error in print_info (line 42)
error([‘Blanchard Kahn conditions are not
satisfied: no stable’ …
Error in initial_estimation_checks (line 175)
print_info(info, DynareOptions.noprint,
DynareOptions)
Error in dynare_estimation_1 (line 165)
oo_ =
initial_estimation_checks(objective_function,xparam1,dataset_,dataset_info,M_,estim_params_,options_,bayestopt_,bounds,oo_);
Error in dynare_estimation (line 105)
dynare_estimation_1(var_list,dname);
Error in a13980809 (line 604)
oo_recursive_=dynare_estimation(var_list_);
Error in dynare (line 223)
evalin(‘base’,fname) ;

Would you please help me to solve the problem?
