Okay guys I found the solution. I explain and later I will edit the proper files and upload somewhere. So the solution step-by-step:

1. Connect to the ftp or wherever your site is.
2. Head to /wp-content/plugins/contact-form-7-datepicker/js/jquery-ui-timepicker/i18n
3. Find the proper language file (for example jquery-ui-timepicker-hu.js is the hungarian file.
4. Open with a text editor
5. On the fourth line write the $.timepicker.regional to this -> $.datepicker.regional and at the 20th line the $.timepicker.setDefaults($.timepicker.regional['hu']); to $.datepicker.setDefaults($.timepicker.regional['hu']);
6. I hope it’s working for you too ??

For the fullness here is the whole german file:

/* Hungarian translation for the jQuery Timepicker Addon */
/* Written by Vas Gábor */
(function($) {
	$.datepicker.regional['hu'] = {
		timeOnlyTitle: 'Válasszon id?pontot',
		timeText: 'Id?',
		hourText: 'óra',
		minuteText: 'Perc',
		secondText: 'Másodperc',
		millisecText: 'Milliszekundumos',
		microsecText: 'Ezredmásodperc',
		timezoneText: 'Id?zóna',
		currentText: 'Most',
		closeText: 'Kész',
		timeFormat: 'HH:mm',
		amNames: ['de.', 'AM', 'A'],
		pmNames: ['du.', 'PM', 'P'],
		isRTL: false
	};
	$.datepicker.setDefaults($.timepicker.regional['hu']);
})(jQuery);

I set up an smtp with Gmail. That was the solution for me. Or you can set up your own host’s mail service if it have one. Here is a little help to do this.

Somehow the general wp_mail function not working.

Same for me but I’m just figured out that if you send to gmail it’s working perfectly for me. But if you want to send to outlook,hotmail or @me it’s missing somewhere. I installed a WP Mail Log plugin and it shows me that wordpress sent the message but I didn’t receive. A little strange.
