Image Effect CK Params - Button not reacting

Hey,
i use Image Effect CK Params, everything was fine. Suddenly the button in the editor doesn't functionate any more. i reinstalled it, but no change. i can see the button, i klick it, but no window opens.
the effects on the pictures work, only the button does not react.
Any idea?
Greetings,

Hi
open the console of your browser and tell me if you get an error when you click on it. Also please check that you have the latest version of the plugin "button editor" for image effect
