We can't help you if you don't help yourself.
You have just said "I installed but it seems broken"
Please read that guide again and explain EXACTLY the steps you took, which of course you wrote down as you went?
We have a pretty good idea of where you are wrong but not making guesses without some careful, detailed explanation.
We're trying to help you here, but that starts with you helping yourself to help us.
Be methodical and careful and precise and tell us the exact steps.
