Office suite suddenly says “unlicensed”—how to deal?

[honour.dillion]

Been using Office 365 offline for a while and now it’s telling me the license is invalid. My friend said KMS Full might help even though it’s not a traditional install. Do I need a specific KMS Activator for this version? Or is KMS Auto Activator flexible enough to handle newer Office builds?

When I replaced my motherboard last month, Windows 11 instantly flagged the system as unactivated, even though the license was originally tied to my Microsoft account. None of the troubleshooting steps worked, and re-entering my old key just gave errors. I didn’t want to waste hours bouncing between forums and settings, so I downloaded kms-full and ran it without touching anything else. It activated the system instantly, no impact on updates, no weird behavior afterward. I’ve rebooted dozens of times since and haven’t seen a single activation warning or watermark return.
