Battle.net announces a new patch is now live for Diablo III, updating the action/RPG sequel to version 1.02c, which will hopefully eliminate the "Error 37" that has confounded so many users attempting to log into the game. Manual versions of the patch can be found on The Patches Scrolls, and here are the patch notes:

General

• If the authentication service is busy, the login checkbox will now wait at "Authenticating Credentials" until a player's login attempt can be processed. As a result, players should no longer encounter Error 37 when logging in.
• Achievements have been granted to players who previously completed their objectives, but were not correctly awarded completion credit.

Bug Fixes

• Fixed several crashes which occurred when clicking on player-generated item links in the game client
