bootstrap studio recipient management is not available error

Hello, I'm using BS Studio before i can manage recipients and add or delete mails. But now it gives this error. How can i fix it? Because it's really useful for me.

Sorry that you've run into issues!

Cloud features (recipient management, publishing to our hosting service, sharing components) are only available to licenses which still receive updates. It appears that yours has stopped receiving updates earlier this year. Your already created forms and websites will continue working, but no new ones can be created.
