Ppt can't install Articulate Add-in

Hi. I have a trial version of Articulate 360. I am hitting the issue where I can't access the content library from ppt. I see the articulate tab in PPT (2016 version), but I cannot access the content library.  I checked the steps above from Lauren Connolly, and that all checked out correctly. Also, I have no disabled items. I uninstalled and reinstalled Studio 360. I still cannot access content library. When I select something, like insert character, nothing happens. So I mouse around, and clicked the Articulate.Presenter.Ipc that popped up, and I get a couple of script error messages (First one: syntax error, char 4498, https://support.office.com/socbundles/support?v=yuxJeASk0aMDZnfyCIa8WI9yh-juNwsNt4gUSger5lQ1. I click yes to continue to run the script. Then I get a "occe' is unidentified error, char: 1652, https://support.office.com/socbundles/article?v=Prn87GNzDCZCaSWAPejfVyQMv4rHdX35goVdKB4jlV81 . I click yes to continue, and these just cycle through 2 more times.  Any ideas ? Is this because I am on the trial license? Thank you!!!
