Can't Open a Word Template in Office 365

I am still using Word 2013, but I am considering upgrading to Office 365 (more for the free storage than the new Office features).  I just came across a post by Rhonda Bracey on her CyberText Newsletter blog about a problem she was having with Office 365 and Word templates. I'm posting this for future reference.

Just a quick note about repairing Office 365—you don’t get a Repair option in the list of programs, despite the user interface text telling you so. Instead, you have to click on Change, say Yes to allow the app to make changes (if asked), then choose Quick Repair from the list. It only takes a few minutes. Once the repair was done, my IT guys told me to reboot the PC, which I did, then I tested the repair by successfully opening normal.dotm.
