When downloading Diablo 2 I get a message that says peer to peer networking disabled. When I click on the “note” I get error 404 page not found. When I try to join battlenet the patch downloads almost all the way then displays an error. I have unistalled and reinstalled multiple times.
That is normal. The p2p mode of the downloader doesn’t work anymore.
Run the game as admin.
When the error occurs just restart the game and it should complete the patch and update.
