[Plugin: NextGEN Gallery] Version 1.9.3 does not work

I use version 3.2.1 of wordpress;
I downloaded version 1.9.3 of the plugin NextGEN Gallery, I have installed, I created my first gallery and my first album and everything worked fine. I opened the edit page of a post I tried to insert the album or gallery to the post by clicking the icon that appears in the menu editor but does not work. I can not select any gallery or albums or single image.
What is the problem?

Sorry for my bad english!
