jQuery allert after enabling Cookie Law

Google arrogates from websites using AdSense a cookie law tool til September, 30.
So I enabled the build-in plugin for the Cookie Law. After enabling the module the browser shows an allert box with following information:

"Developer: Caution! In order to use Cookie Consent, you need to use jQuery 1.4.4 or higher."

How can I update jQuery in this template?

Thanks in advance for assistance!

Versions installed:
Joomla 3.4.3
k2: 2.6.9

Hi,
in that template several months ago we used script from https://silktide.com/tools/cookie-consent/
but I guess it uses JQuery from Joomla itself, not from our template.
But please try to edit that file: gk_musicstate\layouts\blocks\cookielaw.php
and following part:

<?php if($this->API->get('cookie_consent', '0') == '1') : ?>
<!-- Begin Cookie Consent plugin by Silktide - http://silktide.com/cookieconsent -->
<!-- cookie conset latest version or not -->
<?php if($this->API->get('cookie_latest_version', '0') == '0') : ?>
<?php if($this->API->get('cookiecss', '1') == '1') : ?><link rel="stylesheet" type="text/css" href="https://s3-eu-west-1.amazonaws.com/assets.cookieconsent.silktide.com/1.0.7/style.min.css"/><?php endif; ?>
<script type="text/javascript" src="https://s3-eu-west-1.amazonaws.com/assets.cookieconsent.silktide.com/1.0.7/plugin.min.js"></script>
<?php else : ?>
<?php if($this->API->get('cookiecss', '1') == '1') : ?><link rel="stylesheet" type="text/css" href="https://s3-eu-west-1.amazonaws.com/assets.cookieconsent.silktide.com/current/style.min.css"/><?php endif; ?>
<script type="text/javascript" src="https://s3-eu-west-1.amazonaws.com/assets.cookieconsent.silktide.com/current/plugin.min.js"></script>
<?php endif; ?>

Replace with

<?php if($this->API->get('cookie_consent', '0') == '1') : ?>
<!-- Begin Cookie Consent plugin by Silktide - http://silktide.com/cookieconsent -->
<!-- cookie conset latest version -->
<script type="text/javascript" src="https://s3-eu-west-1.amazonaws.com/assets.cookieconsent.silktide.com/current/plugin.min.js"></script>

If will not help, you have to use addcional cookie plugin/module until we do not fix it in future update

Thanks for the reply!

Unfortunately editing the file wasn't the solution. OK: The allert box disappeared. But build-in cookie law tool wasn't seen.

Using a external cookie law tool like Cookie Control from civikuk.com don't work - because it needs jQuery 1.4 also.

you can try to install addcional jquery plugin which will load new version.

Jep, tnx for the info about the additional plugin for installing a new version from jQuery.
I've used "eorisis: jQuery". The build-in cookie-law-tool is now running perfectly.

Thanks again for your assistance!
