The current D7 version of this module only seems to work with the city data files located at http://geolite.maxmind.com/download/geoip/database.

All I need on my site is the country data, but when I try to use anything from GeoLiteCountry or any of the GeoIPv6 files, the module is unable to locate the visitor's country. However, when I use the city data .dat file (GeoLiteCity.dat) the country is identified perfectly. I would love to be able to reduce some of the overhead by not having to load all that city data.
