EDO model doesn't run

I am attempting to run the Fed EDO model described here Federal Reserve Board - Estimated Dynamic Optimization (EDO) Model in Dynare 4.6.4. However, I get the following message:

I think Dynare is not running the steadystate file. How can I solve this?

Did you see

Thank you professor Pfeifer. I initially tried with an earlier version as well but had problems running it. I will try 4.5 and report my results.
