is not responding

Hi guys,

It’s about Diablo 2 Lord of Destruction.

From last night, already more than 24 hours. I have the problem that my CD Key is already using by me. After contact to Blizzard they said that last night they had some issues and can’t do more. Now my message changes to “ is not responding. Please try to connect again in a few minutes”. I still can’t play Diablo 2. Can someone help me please? Thanks.
