Machine activation required for 2018 Essentials??? - Library Account

Hello

Please be aware that the 2018 Essentials manual cannot be opened from my home computer or from my iPad, even though I am trying to open it from my library account.

I can open other manuals, but not this one.

This is what I get:

I hope they do not expect us to request activations every time we use a new computer. When I need to open a manual I need that in the moment, cannot wait days for someone to read these emails.
