Removing powerd By Links After purchasing License?

My license is showing as unregistered and I can not seem to find where to fix that? :(

Please help

Did you add the new license to your site? You need to do it like this:

1. Remove the current license from Administration > Settings > Advanced Settings > Variables
2. Clear the site's cache
3. Logout of the administration panel
4. Login to the administration panel
5. Enter the new license when asked

PEREFECCCTTTTT :) Thanks so much
