MZFinance.BadLogin

Hey,


I recently re-installed my macOS so now I am currently running Yosemite. However, when I click the upgrade button to upgrade to Sierra, it asks me to log in with my Apple ID. When I click login, I get the following error:


MZFinance.BadLogin.MacAppStore_message

I am able to login with my Apple ID anywhere else but not here in the App Store.


Any ideas on how to fix this issue?

MacBook Air, OS X Yosemite (10.10.5), null
