If you have purchased the language packs plugin separately, you will need to install them in to your iDevAffiliate installation. To do so, download the language packs plugin package then unzip the package and inside it you will find a languages folder with all the language files in it. To install your language pack(s), take the provided language file and using your favorite FTP browser, upload it to your includes/languages/ folder.
Once this is done, just log in to your iDevAffiliate admin center and go to Templates > Language Templates. You will automatically see the new language template added to your system.
