Elements 2019: Don't know my serial # to license
I purchased Photoshop Elements 2019 (& Premiere Elements 2019) I downloaded and now want to edit some photos, but can't find how to get started! I only go to a help dashboard, or an offer to either license or start a free trial. When I click on license, it asks for a serial #, but I was never sent one.... I'm sure simple but can't find it, please help!
