Endnote x8 unable to insert figures

So I was able to insert figures up til this afternoon when it stopped working in my current file. I’ve tried restarting MS word, endnote x8 ribbon as well as the computer itself, and it still will not work. The inserting figures function works fine in new MS word documents I’ve created to test, just not the current one.

Each time I attempt at attaching a figure this message pops up:

“Cannot copy content between these two ranges”

And endnote still puts a (figure5) at the end of my selected text, but just not the figure itself.

I’ve tried googling but no one else seemd to have this issue, please please help!

I wouldn’t touch Endnote’s insert figure functionality wiht a 10 foot pool.  They introduced it and never improved it.
