Yeah I realized when I first bought the PRO version...  ???

I am using the "article everywhere" extension to put my gallery articles into custom modules, with the free version of the Simple Image Gallery it was no problem, everything worked smooth and the thumbnails responded correctly with the nice light box pop-up engine. Satisfied with the functions I decided to buy the PRO version as I needed the single thumbnail function for my gallery, it's here the problem starts. The thumbnails that shows up through the article embedded in my module won't work correctly, when clicked on it just opens the image in a new window, no pop-up engine what so ever. I have searched for similar subjects but haven't found any. How can it the PRO version :'( be called to have backwards compatibility with the free version when the versions differ in functionality?

Check the plugin settings and try a different pop up engine please.
