Added Media Player, now asks me to reactivate constantly

I originally installed Windows 8, then upgraded to 8.1. Two days ago I realized I had no DVD player, and purchased Media Player.

Now, everytime I start up - and occasionally while I'm working, I get a screen telling me to go to PC settings to activate windows. When I click on "PC Settings," It shows the last four digits of my product key, with a button to add another key, and says windows can not activate now, try again later.

1) Do I have to enter the product key for Media player
2) Why would it keep saying Windows can't activate?

Any help will be appreciated!

Regards,

Mary

Yes, Media Center needs to be activated using the product key.

Add features - Microsoft Windows

I assume you meant Media Center, not Media player. Might I ask where you bought it from? Just want to make sure it was from a legit source. So you entered the Media Center key though Add Features and now it won't activate, correct? You shouldn't have to enter the product key for Media Center a second time. The Change Product key option is there to let you try a different key, if you have one. Have you used this MC Key on another PC?
