WORDPRESS: NextGEN Gallery Not Function after Upgrade!

My Case:
I upgrade Wordpress 2.7 to wordpress 2.9.1.
The I also upgrade all plug-in that we use in the wordpress includes NextGEN Gallery.

All the previous pictures and gallery still there but the slideshow not working in publish news page.

Solution:

1. Download JW Image Rotator from here.
   
   
2. Unzip and copy the Imagerotator folder in uploads folder.
   Default path is ../wp-content/uploads/
   
   
3. Open the NextGEN Gallery admin panel page. Setting back the NextGEN Gallery Options. Compare the details with the previous gallery setting to get the same effect.
   
   
4. Save all setting. Try refresh the page again. It' s done.
