Error in running fs2000.mod

[yinx]

Hi Everyone,
The above example was running before and now when I tried to run it, it is coming up with the following message:

Error using set_state_space (line 36)
Not enough input arguments.

Error in dynare_estimation (line 75)
dr = set_state_space([]);

Error in fs2000 (line 197)
dynare_estimation(var_list_);

Error in dynare (line 120)
evalin('base',fname) ;

Can someone please explain what's gone wrong?

Thanks.

Are you using Dynare 4.4.1? If yes, please check your path hierarchy.

No, I am using 4.3.3. Thanks.
