Tooltip not showing

Hi Guys.
Thanks for the wonderful glossary plugin. I’ve been using the Pro Edition successfully on my pages, but some days ago (and most likely because of optimization adjustments for page speed) the popup box stopped showing.

I get the following javascript error on the page:

d6eec.js:21 Uncaught ReferenceError: CM_Tools is not defined
at d6eec.js:21
54bfc.js:13 Uncaught ReferenceError: CM_Tools is not defined

at n.fn.init.each (c7035.js:2)
at n.fn.init.trigger (c7035.js:2)
at 54bfc.js:12

Any tips for me to restore its functionality to full glory?
