Dear all:
I am experiencing a problem solving a model with dynare 4

I am the junior user

I use non-linear equations ( even I use linear equations, it still have something wrong), and I get the following error message:


Configuring Dynare ...
[mex] Generalized QZ.
[mex] Sylvester equation solution.
[mex] Kronecker products.
[mex] Sparse kronecker products.

Starting Dynare ...
Starting preprocessing of the model file ...
13 equation(s) found
Processing derivation ...
Processing Order 1... done
Processing outputs ...
Preprocessing completed.
Starting Matlab computing ...

??? Error using ==> ss.inv
Cannot invert system with singular D matrix.

Do you have any suggestions about the causes of this error?
Thanks a lot
