Hi WPRU,
Thanks for using SHTML Slider plugin. We have around 5,351 downloads for this plugin and none of any user find it not working. Even we have tested it with the latest version of WP(3.6). If you are having any problem installing it you can refer its installation section. We have a video documentation for installation and configuration as well. Please follow it and try the updated version of SHTML Slider.
And please do let me now if you still face any problem in its configuration.
And I am expecting a 5 star rating(*****) from you.
Best,
Tikendra
