I uploaded a data set from excel into my map document and tried to batch geocode all of the addresses. For some reason when the geocoding gets to about 37% it just freezes up and the program says 'Not Responding". I have an i7 quad core processor and 12 gigs of RAM on my computer so I know processing power isn't an issue. I can't figure out why it won't finish geocoding behind 30 something percent.???
