[INVALID] GeoIP Plugin Error

I have installed the GeoIP plugin on piwik ver 0.2.28.
Downloaded the GEOIP .dat file, renamed the GeoLiteCity.dat file to GeoIP.dat, and moved it to the /plugins/GeoIP/libs folder.
i have also added the following two lines in /config/global.ini.php:

Plugins_LogStats[] = GeoIP

Then i, activated the GEOIP plugin from the admin settings.
however, when i look at Visitors–>Locations and Provider.
i see the following error:

Error: To publish its public methods in the API, the class ‘Piwik_GeoIP_API’ must be a subclass of ‘Piwik_Apiable’

What does this mean? can someone please suggest way fwd to resolve this, have I missed any steps, instructions??


please install the latest piwik version, it should work!
