Not working... instead of resetting it can you just add a permanent license key for me to use so I don't have to request in the forum all the time? This is getting super rediculous annoying when I plan to reinstall windows.
I have reset it again, please try again.
Remember, you can deactivate MP on your own prior to any reinstall of Windows - just make your Primary a Secondary and it will prompt you to deactivate. You might also have a 'change license' on your about tab (sorry, I dont have the Steam version installed to be certain) to 'Deactivate Local Machine':
