Free to pro

Hello, I a new on this forum... I just buy the PhotFocus Pro theme. I can't integrate my key on the template to activate all options... I see on the website thing to do : After activation, please add and active your License Key for one click update. Plese don’t use Product Key in Liense key For this, go to “Appearance => About Theme”, click on “License Tab”. If you don’t know the license key then you can login to your My Account page and find it there Add License key under “License Key” section, click on “Save Changes” and “Activate License” buttons I don't see : About Theme”, click on “License Tab” Any idée ? Thanks
