Search by location shows Error: Zipcodes table is empty -- Search will not operate.

Hi,

Thanks for this great module.

I successfully uploaded the zipcodes.us.mysql file.
I checked my database using phpmysqladmin and the zipcode table exists and contains data.

My table is prefixed (dru_zipcodes) and I replaced the zipcodes with dru_zipcodes in the zipcodes.us.mysql file as recommended in your readme/install before uploading into the database.

Looks like I succeeded. Table looks good ... but no joy.

Location_search.module seems to still think the table is empty.

Any ideas why?
Workaround?
