Activation for Vista Ultimate
I had reinstalled windows vista and had activated it as well but today i found it to be trying to activate windows. I have checked out complete message and it says that i am having 24 days for activating windows. I don't know why i am getting that message even when i had activated it just some weeks ago. I have tried clicking on "activation link" as well as "Change product key" but they are just not responding.

That error message seems to be common, it occurs when cd rom or installation disc turn bad. You can go through below thread for more information.
