Problem with keywords + referers

Hello folks,

I have got a problem with Piwik. In the dashboard view I can not see with keywords are entered (users that comes from a search engine).
Plus I do not see any referers - what’s wrong?

I looked into the database -> piwik_log_visits -> referer_keyword and I don’t see any entries. After that I checked the colum referer_url and I saw that the URL are url encoded, like this:
http%3A%2F%2Fwww.google.com.ar%2Fsearch%3Fclient%3Dfirefox-a%26rls%3Dorg.mozilla%253Aes-ES%253Aofficial%26channel%3Ds%26hl%3Des%26source%3Dhp%26q%3DmyKEYWORD%26meta%3D%26btnG%3DBuscar%2Bcon%2BGoogle

Could this be the problem?

EDIT:
Solved - problem seems to be a missing .dat file for GeoIP. Weird but after installing the dat file, everything seems to be fine.
