EndNote is not responding. Error = -600

HI!

I’m testing the trial version of Endnote in my computer.

I have a MacBook Air with IOs Yosemite version 10.10.5 and I’ve a licensed Office 2016. The message “EndNote is not responding. Error = -600” keeps appearing whenever I try to do anything with Endnote on Word. It’s instantaneous. I can’t do nothing! I’ve tried to restart and shut down the computer and nothing happened. I haven’t reinstalled the Endnote program yet, but once the other functionallities work perfectly, I’m not sure it would solve anything…

Anyone knows how to fix this?

Thank you very much!
