I also just purchased the GP premium and I have the Lite installed now, but am not sure how to get the Premium installed. Is there a feature to put in the code I received in the email from GP, within Lite somewhere? I have downloaded the zip file, but when I tried to upload to my site, I get this error:
Unpacking the package…
Installing the theme…
Destination folder already exists. /home1/computz5/public_html/newpros/wp-content/themes/generatepress/
Theme install failed.
Thank you for the help.
