Thanks for posting to this public discussion forum, @georgiegin.
I appreciate your use of our services, and I apologize for any confusion. You will need to complete the steps listed at https://helpx.adobe.com/account/individual/subscriptions-and-plans/renewals-and-cancellations/renew-adobe-account-plan-student-and-teacher-discount.html to maintain your discounted rate.
I recommend checking with the educational institution you are attending to see if they offer their own subscription. Organizations that offer their own Creative Cloud subscription often offer greater discounts and increased compatibility for students and other members of the organization.
