The game, which features elements of the hack and slash and dungeon crawl genres, was released in North America, Latin America and Europe on May 15, 2012, and is scheduled to be released in Russia on June 7, 2012.

Before its release, the game broke several presale records and became the most pre-ordered PC game of all time on Amazon.com.

Initially the launches were hindered by heavy server load with many users getting various errors, including the error 37 “The servers are busy at this time. Please try again later”.

Diablo III Error Codes and Bug Fixes

The following errors have appeared since Diablo 3’s launch on May 15, 2012.

Error 37

This error indicates that the Diablo III server is full and is likely the result of high login traffic. If you receive this error message, please wait and try again.

Error 3005 and 3006

These are server time outs. If you receive either of these messages while playing, please wait and try again.

Error 14009 and 315300

We’re still looking into these issues, but a player workaround is available in the meantime. If you are experiencing either of these issues and are using Windows, create a new user account with administration powers (http://www.wintuts.com/Manage-User-Accounts). From there, log into Diablo III.

“Unable to find all of the appropriate game configurations to create or join games.”

Error 3003 – Servers Offline

Unable to connect to the service or the connection was interrupted.

This error is caused by the servers being offline, and not allowing players to connect to them until they are brought back up. There is no fix for this, but the current status of each of the three game servers can be found here:

Error 12 – No license attached

People in Asian regions with a digital version of Diablo 3 have been receiving this code. Blizzard’s Game Masters can manually flag accounts to fix this. There is no other solution at this time.

Error 75 – Battle.net Outage

Battle.net is down and will not allow login to Diablo 3.

Error 108 – Unable to open installer tome2.mpqe

  • Solution: This seems to be a short-lived, temporary error.

Diablo 3 Beta Errors

These errors were present in the Diablo 3 Beta, and may or may not also be present in the full game.

Diablo Error 3003

In the full version of Diablo III, this error occurs when the servers for Diablo III are offline, and this issue cannot possibly be resolved.

  • Solution: Games will not switch your location automatically when you log in, so you must manually enter your location (e.g. Americas).

Diablo Error 3004

  • Solution: This seems to be a short-lived, temporary error.


These issues made the game unplayable for those affected while some others experienced in-game bugs.
