title: OpenX and geotargeting problem
body: <p>I downloaded the latest version of OpenX 2.8.6 and I am trying to setup geotargeting, but it doesn't work. I enabled geoTargeting in administration panel ( Configuration -> Global settings -> Geotargeting module type -> OpenX Max mind (flat file) ). I read in documentation of OpenX that it's not necessary to put any path to the database in plugin settings, so I tried without. I setup delivery options of test banner to be shown only in Serbia. I am refresshing the page that displays banners, but this banner never shows.</p>
  
  <p>I thought that maybe the problem is in old database and that my IP address is not recognised, so I downloaded the latest one database (.dat file) from MaxMind (lite version of Country database) and put the path in settings of the plugin, but it still doesn't work.</p>
  
  <p>Can anyone help me how to resolve this problem?</p>
