MJDGGES returns the following error code 11

Dear friends,

I am getting the following error message when I run my dynare code:

??? Error using ==> print_info
MJDGGES returns the following error code11

Error in ==> c:\dynare\4.0.4\matlab\stoch_simul.m
On line 44 ==> print_info(info);

Error in ==> c:\dynare\4.0.4\matlab\ramsey_policy.m
On line 25 ==> info = stoch_simul(var_list);

Error in ==> C:\MATLAB6p5\work\DSGE_Stackelberg\fiscalleadership.m
On line 144 ==> ramsey_policy(var_list_);

Error in ==> c:\dynare\4.0.4\matlab\dynare.m
On line 102 ==> evalin(‘base’,fname) ;

So, I would like to solve this problem but unfortunately i do not know how to start…
Does anyone have a solution, clue, and so on?
My sincerely regards to all dynare community…
