Image Show GK4 Add new slide is not working

Hello!
I have installed Youshop template Joomla 2.5 version. I have problem with Image Show GK4 module. Add new slide doesn't effect, there is nothing happens. I tried ti uninstall old version and installed new updated version of this module. Then first tima Add new slide opened me options for adding image or article. After i saved but it gave me back no saved slides and Add new slide button doesn't work again.

Please, help me solve this problem.

Regards,

Ruslan
