Mootools and scripts

Hi,
I just bought this template (real design) but when i want to save my proper "slideshow" with Image Show GK4 type, and Joomla! 2.5.6 it answer me that i have a script problem : "Script : http://localhost/sitename/media/system/ ... ore.js:170"
I already try to desactivate mootools or to use last extensions provided to desactivate but unsuccessfully.

For information i am on local WAMP SERVER :
Jeu de caractères pour MySQL: UTF-8 Unicode (utf8)
Serveur web
Apache/2.2.11 (Win32) PHP/5.3.0
Version du client MySQL: mysqlnd 5.0.5-dev - 081106 - $Revision: 1.3.2.27 $
Extension PHP: mysqli
phpMyAdmin
Version: 3.3.9

Do you have an idea ?
Thanks.

Hi,

I haven't seen the same problem before so I don't have any idea now, if you could put the site online and give me access I would debug to find out the cause for you.

Thanks,
