aescripts+aeplugins Floating Licenses are intended for larger enterprise customers who need to be able to control licenses for a large number of users from a central location. If this is not you then you probably don’t want to use this license type.
If you are an individual user you should consider the Single User License (SUL). The SUL license allows for the software to be installed on up to two user accounts/computers as long as they are not being used at the same time. If you need to install it on more than two user accounts or computers you will need to purchase additional SUL licenses or consider the Floating licenses.
Floating licenses differ from single user licenses in that they can be dynamically moved between users and machines. Floating licenses can only be used in conjunction with the Floating License Server.
A license can only be used by one user at a time, so make sure you get enough licenses to cover your number of users. The aescripts+aeplugins Floating License Server is Free with purchase of 5 or more Floating licenses.
