Adobe Connect free trial: How many people at once ¿?

Hi,

I´m testing Adobe Connect Webinar using the free 30 day trial, and although it informs about the possibility to "connect with up to 24 other people at once", I can´t do it with more than 4 simultaneously (1 host and 3 participants).

From this moment, every user that try to access using the link of the session obtains the following message: "The user limit for this meeting or seminar session has been exceeded. Contact your meeting or seminar organizer for assistance".

Could you please tell me if I am doing something wrong? May be it´s normal for this trial time? I don´t really understand how does it works about this question...

Thanks!
