Blanchard Kahn conditions are not satisfied: no stable equil

hi;
i have a problem when i run my code:
the error message is:
??? Error using ==> print_info at 42
Blanchard Kahn conditions are not satisfied: no stable equilibrium

Error in ==> stoch_simul at 98
print_info(info, options_.noprint, options_);

Error in ==> a at 321
info = stoch_simul(var_list_);

Error in ==> dynare at 180
evalin(‘base’,fname) ;

the code is about nigeria dsge model
nigeria dsge.mod (1.42 KB)

As always in these cases, check the timing in all of your equations.
