Subscripted assignment dimension mismatch

Hello. I am a beginner, and I am trying to run this model in dynare 4.1.3. It seems that the rank condition is satisfied and I can obtain the policy functions, the theoretical moments, the matrix of correlations and the coefficients of autocorrelations, but then I obtain the following message:

??? Subscripted assignment dimension mismatch.

Error in ==> simult_ at 44
y_(:,1:M_.maximum_lag) = y0;

Error in ==> irf at 51
y2 = simult_(temps,dr,ex2,iorder);

Error in ==> stoch_simul at 130
y=irf(oo_.dr,cs(M_.exo_names_orig_ord,i), options_.irf, options_.drop, …

Error in ==> model at 97
info = stoch_simul(var_list_);

Error in ==> dynare at 132
evalin(‘base’,fname) ;

Can someone help me?

Many thanks,
