Responsive Banner Slider / Problem

Hello,
Yesterday I have purchased Responsive Banner Slider (for 4,90 $). However when I publish it, my shopping cart show "0" quantity and "0" amount even there is a selected item in my cart. When I deactivate the responsive banner slider, my cart becomes normal (I see quantity selected and the amount of the selected items).
What can be the problem? I need your urgent and kind support please. I'm blocked completely. Thank you very much.
best regards,

Hello

thanks for your purchase....
can you setup a page for us and fill the URL on the Site Details below so we can take a look at the problem?

thanks

Thank you for your kind reply. Is it possible to advise us how to do it ourself? If you can show the way by some explanation, I guess we may try it.
looking forward to hearing from you.
thank you.
best regards,

Okay...
are you able to see the html source of that page?
if you're able to do that then can you check in the header part of your site if there's a jQuery library been loaded more than one? maybe there's one from this module and from your template or from Virtuemart...then de-activate them and leave the first in the order.

let us know then
