Try commenting out the babel package. I think apacite has problems with babel and hyperref. I commented those packages out of my document and my citations formatted correctly. I don't understand why, but it worked for me.

Use the url package

\usepackage{url}

Then you can insert the \url command in your bib entry. For example,

@misc{ACS,
author = {{\bibcorporate{U.S. Census Bureau}}},
year = {2006},
title = {{A}merican {C}ommunity {S}urvey, {S}chool {D}istrict {D}emographic {S}ystem},
howpublished ...
