Redmine

Hi Guys,

It is my first post here, please be nice.

I am trying to report activities of all users on all projects.

I have noticed that there is no an option in standard redmine system to do that.
So i installed plugin:
http://www.redmine.org/projects/redmine/wiki/PluginTimesheet

And of course it is not working (please see the image in attachment).
There is problem with "translation missing: pl.timesheet_title"

I checked the file pl.uml and there is:

timesheet_title: Czas Pracy
timesheet_date_from_label: Od
timesheet_date_to_label: Do
timesheet_project_label: Projekt
timesheet_activities_label: Aktywności
timesheet_users_label: Użytkownicy
timesheet_showing_users: 'czas pracy użytkownika: '
timesheet_permalink: '(Permalink do tego czasu pracy)'
timesheet_group_by: Grupuj

I don't know hot to set up this.

Furthermore, if i go to administration-->settings--> and I give Configure attached to Redmine Timesheet Plugin there is error 404:
"The page you were trying to access doesn't exist or has been removed."

System: windows 7
Bitnami redmine is installed.

Please good people,
help me,
Best Wishes
Jacek Antek
