Diablo 2 Your Cd Key is currently being used by you error

Hey i recently installed my new copy of Diablo 2 and after updating to latest patch and tried logging in to bnet, i get this message. Tried restarting router/game/pc also waited a couple of hours and nothing worked.

Any help?

try making a ticket and waiting 24 hours for a response.

Still can’t login after 15 hours, i submitted a ticket hope it gets resolved.

Edit : After 36 hours still can’t login, support didn’t help so far.
