I Installed the component and create a test form. but it shown this

"Persian translation is still missing. Please consider to contribute by writing and sharing your own translation"

I coped the en-gb files to fa-ir folder (my language) and edit the com-...xml files and tried reinstall it. this time it shown this

"Persian translation has not been installed, but is available. To fix this problem simply install this extension once again, without uninstalling it"

OK. i translate it and reinstall it. but nothing changed.
