Group licensing is a subject that needs Adobe input. We are not Adobe. Just user to user.
Please contact Adobe via its Adobe Chat.
I am not sure which topic best fits your inquiry - perhaps Orders, Refunds, and Exchanges.
To get to Adobe Chat, click on the statement "Still Need Help? Contact Us."
The following is a link to the Premiere Elements 11 tryout which has been used by individual users from time to time under certain circumstances. But none were coming from a group license setup.
The web site cited does not sell the tryout. It just makes it available for use. And, if the user does not or cannot carry out the required instructions, the user ends up with an Access Denied.
