Ok, so i reïnstall my computer once every 1-2 months...
So i downloaded HM and wanted to insert my key...
i got this message:
so what do i have to do now? How can i fix this?
I don't want to pay again for something i already own.
EDIT: i actually never used my key for any other pc then the one that i reboot every month... So i was kinda suprised
