I changed the domain where I'll be using Pro, so I deleted the theme on the initial domain and change it on my profile, assigning the license to the new domain.
I downloaded the latest version of Pro and uploaded it using the wp theme's installer.
After uploading I received the message: "session expired, try again".
Uploaded another theme to verify what might be happening and everything was normal.
Tried several times to install Pro again with no results, always getting the same message.
Please, may you advise on this?
