First, let me say I've been fixing or trying to fix issues with the PL Carousel in Framework where NextGen is the source for over a year. That gallery has had issues, not just with PL but with other themes, platforms and systems for a while. I'm not saying they're at fault or have a bad product. It is simply that it doesn't work 100% with every website, or every system. A thousand and one variables could impact it, through no fault of NextGen, nor of PageLines.
The problem that is affecting Framework isn't the Carousel. It's the use of NextGen as the source of your thumbnails. If you switch to Posts, you'll see the carousel works perfectly.
More than likely, you simply need to visit their website, download an older version and replace the new one. Another option is to deactivate the plugins other than Nextgen and see what happens to the carousel.
