The steady state contains NaN or Inf

Dear all:
When I run the HSTBayes.mod------which is a example in dynare, it is coming up with the same errors{I have uesd the model_diagnostics(M_,options_,oo_)、model_check to check the model,there is no problem.}:

Error in computing likelihood for initial parameter values
??? Error using ==> print_info
The steady state contains NaN or Inf

Error in ==> initial_estimation_checks at 69
print_info(info, DynareOptions.noprint)

Error in ==> dynare_estimation_1 at 169

Error in ==> dynare_estimation at 70

Error in ==> HSTBayes at 205

Error in ==> dynare at 120
evalin(‘base’,fname) ;

I don’t know what the problem is.I am very puzzled .

the HSTBayes file attachment as follows:
HSTBayes.mod.rar (8.51 KB)

This is not an official Dynare file in use. The problem is that the model itself is linear, but there are constant terms. For estimation to work, you need a steady state file. I attach an updated version. But there are most likely still problems.
HSTBayes.mod (1.96 KB)

Dear professor pfeifer:
Yes, There is a collinear equation in HSTBayes.mod. Under your tip,I know how to solve it. Thank you very much!
