[Plugin: WordPress Content Slide] Content Slide for Twenty Eleven theme

I’ve found that I can get Content Slide to work for the theme Twenty Ten but it doesn’t work at all for Twenty Eleven. Has anyone else had this issue and is there something I can do differently?

Yep, don’t edit the core files, use child themes to make changes, I know.
