Problems with translation of plugins

Hello guys, i want translate a popup contact form as i wish, but my translation doesnot work properly.
I translated with poedit.
I had a .pot file which contained only some keywords.

here it is

#: contact-popup.php:43
msgid "You do not have sufficient permissions to access this page."
msgstr ""

#: contact-popup.php:62
msgid "Settings"
msgstr ""

#: contact-popup.php:93
msgid "Message not sent: Please enter your name."
msgstr ""

#: contact-popup.php:98
msgid "Message not sent: Please enter your email."
msgstr ""

#: contact-popup.php:103
msgid "Message not sent: Please enter your message."
msgstr ""

#: contact-popup.php:110
msgid " Contact Form Submission"
msgstr ""

#: contact-popup.php:117
msgid "Message not sent. An unknown error occurred."
msgstr ""

as u see this things are in contact-popup.php

I need to translate ALSO contact-form.php in same dir.

here is my add code

#: contact-form.php:33
msgid "Name:"
msgstr "Имя:"

#: contact-form.php:44
msgid "Email Address:"
msgstr "Email Адрес:"

#: contact-form.php:55
msgid "Message:"
msgstr "Сообщение:"

#: contact-form.php:66
msgid "Are you human?"
msgstr "Вы не робот?"

#: contact-form.php:77
msgid "Send Message"
msgstr "Отправить"

is it okay to do such a thing? because it doesnot work at all. And how to find a correct line for keyword, becuse my Notepad++ has different lines for keyword.
