Missing Language files in admin area

I have purchased the extension earlier for my Joomla 2.5 site. My admin backend is giving language file problem. I have checked there is no files in admin language folder for this custom properties component.

Will you provide me the language pack for the extension compatible with the custom properties Joomla 2.5 version.

*** not the solution ***

Thanks for the response.

But i don't have the package and due to subscription expiration i am not able to download that again. So please provide me the language files only for the administrator of custom properties compatible with Joomla 2.5 version. if possible.
These two files i needed.
/administrator/language/en-GB/en-GB.com_customproperties.ini
/administrator/language/en-GB/en-GB.com_customproperties.sys.ini

Thanks in advance

I gave you the wrong solution.
I'm sending you the files by email.
