Please, double check under the Licenses tab > Details... all License Details - License Data - Subscription end values. Reactivating your license(s) will update its maintenance plan end date and should fix your issue. Feel free to reuse the license code you received with the software, it's valid forever (the code remains the same all the time). Also, any time needed you can use the Resend keys button under User Panel - My Licenses.
Hope that helps.
