Transitions not working

Hi, I noticed that lately the hot effects slider module is not working. The 1st picture get displayed however the transitions do not work. Even the module's buttons disappeared. I'm using Joomla 1.5.23

When I purchased and installed this module, and configured it, it used to work fine. I just realised that it's not any more. The site I'm using it in is www.mountainbikewill.com and it's the wide picture exactly beneath the main title.

Any help will be greatly appreciated.

ok solved the problem. Hot Effects Slider was conflicting with another module: mod_iyosis_google_translate that had the following options enabled:

jQuery library
jQuery.noConflict

Disabled these options and all works well now. Thanks.
