NextGEN problem selecting gallery

I am trying to include a gallery in a new post. In “posts” I click on “Add nextGEN gallery” and it brings up the pop up box. My problem here is that I cannot select the drop down box. My cursor goes from an arrow to a I when I hover over the drop down option.

I have tried inserting manually as in manually typing [nggallery id=44]. I get an error saying error 404 nothing found.

help?
