NextGen slideshow widget

Hello, I recently added the slideshow widget on a site, it worked fine the first day when I did the transition, but the day after, all I get is a loading animation, regardless if I use the imagerotator.swf or not.

Nothing was changed since it was working to when the problem arrose. Here is the site on which I have the problem https://www.designinterventionmoncton.ca.

I tried some of the ideas that I found trough-out the forum, all files and folders are schmod 755 and went through the setting and made sure that the uploads are directed to wp-content/uploads, I’ve tried with the flash and without. No success. Any ideas as to why it is behaving like this?
