Thank you for posting, @céline21.
I understand how frustrating it can be when you expect credits to renew and they do not appear the way you anticipated.
I reviewed the subscription history and can confirm that the Firefly credit plan was canceled on May 22. A new Creative Cloud Pro subscription was started yesterday, and generative credits are currently available on the account.
Those credits can be used for Firefly video generation, although video features consume credits at a higher rate than some other Firefly actions. You can learn more about generative credits and how they are used here:

If you are able to generate videos successfully, then the available credits are working as expected. If you continue to experience problems using them, please let us know what happens when you attempt a generation and whether you receive any error messages.
Please feel free to update this discussion if you have any additional questions, @céline21.
