I've tried to set Views Showcase, the showcase block shows up without effect and with error below :

Notice: Trying to get property of non-object in views_showcase_get_libraries() (line 204 of /home/xxxxx/sites/all/modules/views_showcase/views_showcase.module).
Notice: Trying to get property of non-object in views_showcase_get_libraries() (line 209 of /home/xxxxx/sites/all/modules/views_showcase/views_showcase.module).

Those 2 lines are "$libraries['cycle'] = $file->uri;" and "$libraries['easing'] = $file->uri;"

About Libraries, what I did, I downloaded file "jquery.easing.1.3.js" and put it in "site/all/libraries/easing" Also, download "jquery.cycle.all.js" and put it in "site/all/libraries/cycle"

Any idea how to fix it?

Thanks
