Preprocessing failed

Hi, the following error occured after running my model;
ERROR: There are 42 equations but 43 endogenous variables!

Error using dynare (line 174)
DYNARE: preprocessing failed
But I have 42 variable in var block.
thank you for your help

It seems you have not uploaded the same file. For the attached file, I rather get with the unstable version:

[quote]ERROR: If the model is declared linear the second derivatives must be equal to zero.
The following equations had non-zero second derivatives:
* Eq # 37
* Eq # 38[/quote]
