Plg GK Reservation Language files

Hi, I'm using Steak Hose in an IT website and trying to translate the plg GK reservation, someone can provide the following files?
en-GB.plg_system_gkreservation.ini
en-GB.plg_system_gkreservation.sys.ini
to translate and duplicate in it-IT folder ... I don't have them in my folder language/en-GB
Thank you

For future reference they are available in gk_steakhouse_rest_files_J!3.zip in Steak House download page.

See attached file which contains language file for en-GB.

See you around...

Thank you very much Norman!

No problem at all, let us know if you need further help. See you around...

Hi, I'm also using Steakhouse 2.5 in an italian site, and a did exactly (so I hope) what you say: picked the two en-GB files, I translated them and copied in the sitename/language/it-IT folder. And the system doesn't translate my reservation plg.

Here's the url of the page:
http://www.angelodelconvento.it/test/index.php?option=com_content&view=article&layout=gk_steakhouse:one-page&id=113&Itemid=1027

What's wrong? Could you help me please?
Thank you

Same thing and I see you have no answers after one year...

I have changed the language and there is no modification on the formular.
I change the files :
fr-Fr.plg_system_gkreservation.sys.ini
and
fr-Fr.plg_system_gkreservation.ini

With a translation from EN to FR.
PLG_GKRESERVATION_DATE_PLACEHOLDER="Date"
PLG_GKRESERVATION_TIME_PLACEHOLDER="Heure"
PLG_GKRESERVATION_SIZE_PLACEHOLDER="Nombre de personnes*"
PLG_GKRESERVATION_NAME_PLACEHOLDER="Nom"
PLG_GKRESERVATION_EMAIL_PLACEHOLDER="E-mail"
PLG_GKRESERVATION_PHONE_PLACEHOLDER="Téléphone"
PLG_GKRESERVATION_TITLE_PLACEHOLDER="Sujet"
PLG_GKRESERVATION_TEXT_PLACEHOLDER="Demande spéciale"
PLG_GKRESERVATION_SEND_BTN="Envoyer la réservation"
PLG_GKRESERVATION_RECAPTCHA_ERROR="Invalid reCAPTCHA code"
PLG_GKRESERVATION_MESSAGE_SENT_ERROR="An error occured during sending your message: "
PLG_GKRESERVATION_MESSAGE_SENT_INFO="Your message has been sent!"
PLG_GKRESERVATION_NO_RECIPENT_INFO="The owner of this website didn't specified the recipient of your message."
PLG_GKRESERVATION_STANDARD_SUBJECT="Message from reservation form on: "
PLG_GKRESERVATION_MESSAGE_EMPTY_ERROR="You didn't filled all necessary fields - all fields are required."
PLG_GKRESERVATION_NAME_LABEL="Nom: "
PLG_GKRESERVATION_EMAIL_LABEL="E-mail: "
PLG_GKRESERVATION_TEXT_LABEL="Texte: "
PLG_GKRESERVATION_DATE_LABEL="Date: "
PLG_GKRESERVATION_TIME_LABEL="Heure: "
PLG_GKRESERVATION_SIZE_LABEL="Nombre de personnes: "
PLG_GKRESERVATION_PHONE_LABEL="Téléphone: "

I have also change activated the language into the backoffice and also changed the file
/plugins/system/plg_gkreservation/plg_gkreservation.xml
like this
"<languages>
<language tag="fr-FR">language/fr-FR"/fr-FR.plg_system_gkreservation.ini</language>
<language tag="fr-FR">language/fr-FR/fr-FR.plg_system_gkreservation.sys.ini</language>
</languages>"

And it doesn't work.
Dont know what to do...
