Can't get geocoding to work without Zips

I'm trying to geocode historical addresses for Manhattan and Brooklyn that do not include zip codes.  Based on the instructions in this other thread: http://forums.arcgis.com/threads/13639-Geocode-streets-without-knowing-ZIP , I made a dual range locator (using Tiger 2010 lines, Kings and NY counties merged) and left the zip fields <none>.  When running the geocoding process, I left the zip field blank again.  None of the addresses match up at all- no errors, just 100% failure.  To make sure my addresses were okay, I filled in a few zips and ran again using a similar locator that did include the zip field- those addresses with zips geocoded fine. 

What do I need to do to get all of my addresses to geocode successfully, without zipcodes?  I'm running the trial version of Arc 10 which is supposed to have been updated with all of the service packs.
