Answer:
The license is transferred to the user's computer when logging in and remains there until the license is returned, the program is closed, the rent period has expired, or the effective time has expired in the event of a crash. The rent time is a maximum of 30 days and the active time is 24 hours. Then, the license is free again and can be assigned again.
Without further help from us, you have to wait a maximum of 30 days before using it again.
