Multilevel binary logistic Regression

I wish to run multilevel logistic regression with my dependent variable being suffering from hypertension (0=no, 1=yes) for the population residing in different states. I run the following command on stata 14.
melogit hyper || shdistri:

However, I got the following error message
Unknown #command
unexpected end of file
(error occurred while loading ssd.ado)

I have even increase the memory is allocated to ado files type. Still it is showing the same error. Please let me know how to deal it.
