sentence structure

The rason I am asking this question is that I am not quite sure if what I said to a friend of mine a few days ago was grammaticaly correct. My friend doesn't know how to install a computer hardware. I didn't know that. Below is what I said when I saw him.

" You should have told me that you don't know how to install it. I could have helped you."

After saying it, I was in a big dillema because I wasn't sure if I should have replaced DON'T KNOW with DIDN'T KNOW.

Please help.

eagerness "You should have told me that you don't know how to install it. " " Should have " is a hypothesis of the past, hence the subordinate verb should also be in the past for reasons of concordance. Simple past and past perfect both are usable here.
