[Plugin: ShowTime Slideshow] Slideshow disappeared

Hi, I’ve been running this plugin with no problems for some time, but suddenly all the slideshows have disappeared – stopped working.

I’ve tried the de-activating-reactivating of other plugins with no success, but can’t quite figure out what else I should do.

I do like the plugin and would really like to continue using it – might anyone have any idea how to get it to work once more?
