Can't get icons to load in Presenter

I'm trying to add icons to my PPT from the icon library but every time I try to add certain ones, I receive a message stating "We're sorry, something went wrong with Articulate Presenter and it might close." I can add some icons but not the ones I need. Any ideas on what's causing this?

I've tried this and it didn't work.

1. In PowerPoint, go to the File tab on the ribbon and click Options.
2. Select the Add-Ins tab on the left side of the window that appears.
3. Go to the Manage drop-down again, and select COM Add-ins and click Go.
4. Uncheck Articulate Presenter IPC Handler.

Close PowerPoint and reopen PowerPoint. Repeat steps 1-4 but this time make sure to check Articulate Presenter IPC Handler.
