No valid license Found after resetting PC

I just Recently reset my PC due to some issues. After that I reinstalled everything and did the usual reactivation stuff that I have done many times before. I entered the new E-Licenser Name and added my Licenses. Well now it says that the License was used once for installation and that i need a new activation code to actually start it. I never had that before and have found nothing on the internet that has helped. If anyone knows what i should do, please help me.

I’ll sent you a PM!
