After years of use, my MS-Office 2013 suddenly claimed to be not yet activated and threatened to stop working. I tried to activate it, but this proved impossible. (First it was 'this code is already registered, then 'not a valide product code'.)
However, my fiddling must have helped somewhat as next day everything seemed alright again: no error messages when starting any Office application and when clicking 'Account' I see the reassuring text 'Product Activated'.
Yet I fear not everything is right. When clicking 'Additional licence data' I DO get a warning against an alarmingly pink background: 'Activation required'.
So: is my Office safe or not?
