I have been using your Card Lock System for over a decade, and it has served me well. Unfortunately, I've recently encountered issues with the card management program, which seems to indicate that the license may have expired. Could you please let me know if there's a possibility to extend the license for this older product? I'd appreciate any guidance on how to resolve this issue, as I'd love to continue using the system without interruption. Thank you!
