Cd key problems on D2

hello, i never have problems with my cd(16 characters) key and i have it for 15 years, my instaler its in spanish and i tryed to download the english version on the battlenet web and when i try to install it he ask me for a 24 characters cd key i dont know what to to do any support plz?

yeah, i got the same problem and normal support way wont work, cuz we cant upload error files, cuz its not an error from the game. The old installation from cd works for example, but its not playable with new pcs. plz blizz help us.

Claiming your old 16 digit CD Key (via the Redeem a Code box here) onto your Battle.net account will convert it into the newer longer form, which you can then see on your Games page here: https://account.blizzard.com/games#classic-game-accounts

You then use that new longer form CD Key in the newer installer from the Downloads page.

Could we hear something about the widespread connectivity issues? Dozens of complaint threads were open in the last couple of days on the US boards https://us.forums.blizzard.com/en/blizzard/c/support/49
