I'm trying to activate my SDL Trados Studio 2017 upgrade, and I'm getting the "The start date for this license has not been reached" error. I see in the knowledge base that the solution is to reset the license, but pray tell, how do I reset my license? I can't find a "Reset" button on the website or in the software. (For future reference when others encounter this, please a) explain what triggers this error and b) answer with exact menu commands to save time and frustration.) Thanks!
