Hi ! We have the license DE, and the watermak "Aximmetry Channel" is always on screen. why ??

Dear Modulo, 

You might have entered the wrong in your machine (community DE). Please deactivate the key (press Help -> Deactivate License) and try using your paid Broadcast DE key and the watermark should be gone.

Hi !
