unknown column proximity

I am running 6.x.2.x-dev, my coordinates are based on the location module (separate issue - I need help migrating 10,000+ node locations based on location to gmaps)

My primary problem is that I have a view argument based off taxonomy term,
I have 'Marker option: Point option' and 'Map option: Center on view location' set
Map renders on on the node type I include my view but it is not centered on the node.

I read that I have to add another argument 'Content Point: Proximity by distance' and click 'Set view location to the first used point during execution.' checkbox.

if I say that the default argument is the node ID and I set a limit on the distance then save the view, I get this on my output

user warning: Unknown column 'gmaps_content_point.proximity' in 'where clause' query:

Gmaps_content_point table has zero records in it, and it doesn't have a proximity field.

If my problem is because I am using the location module, how can I use proximity with locations - or - how do I port my existing data setup to use location.

Thanks
