Horizontal Film Strip Stylesheet URL

Hi,

I’m using NextGen Pro for my client’s site. The problem is, even after moving the site from my development server to their server, the stylesheet file for horizontal film strip module is still connected to the one on my server, i.e., its url is the old one. It seems like galleries that are created after moving the server use the css file on the new server, and the issues is only with galleries that were created while the site was on my server. This is the site:

For example, inspect this slideshow, and look at the path of the stylesheet:

http://www.stefanbeckman.com/interview-magazine-february-2010/

The stylesheet is on project.coolgrayseven.com, not on http://www.stefanbeckman.com

Is there any way to fix it?

Thanks!
