Unable to add licence

[Aspro 0]

Hi I'm trying to add my licence. I fill my licence number and button Add licence just do nothing. I turned off all extensions in FF. Checked console and there is no error. In network there is only one empty POST request.

Where exactly are you trying to add your license? In the license manager at my.eset.com or in ELA or EBA?
