License deactivation problem

Hi,

For my following license xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx activated on 06.02.2016, I need to deactivate the license.

I tried to do so, but received an error message during my offline deactivation. Could you please deactivate it so I can move forward with this process?

Thanks in advance for your fast problem resolution + confirmation per mail.

Best regards,

Mitsuko Moser
