Hey Armin,
I've been trying to input my licence key, but when I click "Activate" the page reloads without changes, and the warning about "unregistered version" is still there in the backend.
Also, I don't know why, both in Safari and Firefox I can't see the images of my carousels anymore? Thanks for the help.
