In the German language file the translations of North and South America (lines 511, 512) are mixed up:
511 'UserCountry_continent_ams' => 'Nord-Amerika', 512 'UserCountry_continent_amn' => 'Sd-Amerika',
ams should be "Sd-Amerika", amn has to be "Nord-Amerika".
please submit all translations updates to firstname.lastname@example.org ; translations mistakes are not bug (that would be way too much noise in trac). thanks
