EndNote X7.5.1.1 crashing with Office Mac 2011 (OS El Captain)

Could anyone please help solve the issue with Word crashing each time I try to insert/edit citations from EndNote X7 library. Problem progressed to EndNote X7 crashing too now each time I double click any citation.

Have several manuscripts that need completion and can’t believe this is happening. I have read through earler threads but cannot follow the steps of converting to unformatted and copy pasting new Word document since Word crashes within a second or two of any function to do with CWYW.

Thank you!

Call tech support.  These kind of errors are almost impossible to communicate about in a forum.  

Same thing is happening to me, but with Word 2016. Word 2016 for Mac crashes immediately after I try to insert references.
