Problem with Steady States

Hello, I am trying to build my first model, but I have problems with the code, which tells me this:

Residuals of the static equations:

Equation number 1 : -0.01 : c
Equation number 2 : -0.53333 : w
Equation number 3 : -1.8 : 3
Equation number 4 : -3 : q
Equation number 5 : -1.0156 : pi
Equation number 6 : 0 : 6
Equation number 7 : 0.1 : a
Equation number 8 : 0.2 : mc
Equation number 9 : 2 : sf
Equation number 10 : 0.77101 : tau

Warning: Matrix is singular to working precision.

In steady_ (line 55)
In steady (line 80)
In rbc.driver (line 229)
In dynare (line 293)

Residuals of the static equations:

Equation number 1 : NaN : c
Equation number 2 : NaN : w
Equation number 3 : NaN : 3
Equation number 4 : NaN : q
Equation number 5 : NaN : pi
Equation number 6 : NaN : 6
Equation number 7 : NaN : a
Equation number 8 : NaN : mc
Equation number 9 : NaN : sf
Equation number 10 : 0 : tau

Error using print_info (line 32)
The steady state has NaNs or Inf.

Error in steady (line 102)
print_info(info,options_.noprint, options_);

Error in rbc.driver (line 229)
steady;

Error in dynare (line 293)
evalin(‘base’,[fname ‘.driver’]) ;

I attach the mod file; thank you very much for the helprbc.mod|attachment (862 Bytes)rbc.mod (862 Bytes)

Are you sure that your model is log-linearized correctly? There are still some residuals, I think, coming from the parameter tau.
