While attempting to play the D3 beta, I'm getting error 3004 when attempting to start a game. This is happening after choosing my character, and clicking resume game.
This error message is very succinct, but I can't help but want more information. Is this an error from my end, or does it originate from Blizzard's servers? More details are needed so I know what action to take.
Error 12 - This is an error we're still investigating but you can
workaround it by simply changing your Battle.net account password to
force your account information to refresh. Once changed you can
change it back.
Error 33 and 34200 - The service is undergoing maintenance, please
try again later.
Error 37 - The server is full. This is likely due to us lower the
concurrency cap to address an issue or error. The only solution is to
keep trying to log in.
Error 24000 - Once logged in you may run into this error when
attempting to start a game. We're aware and are working to resolve it
as quickly as possible.
Error 3003 or Error 75 - Click Options, under Account change your
region to The Americas. The open beta is only being held on US
Error 3004, 3006, 3007, or 300008 - These are all related to timeouts
or creation errors for characters or games. These are server-side
issues, and need to be resolved on the game side. There are no
workarounds for these errors except to try again.
Error 315300 - If you're sure you're typing your correct account
information, check to ensure no additional spaces were added before
or after your email address. If you're still running into this issue
there may be an error in your foreign language appdata files. Some
players have found a workaround but please be aware the steps they
provide are not something we can currently support.

your account name. Your BattleTag is a nickname, not your account

Please remember to get and use the beta client, not the pre-download
It's best to let the launcher finish the entire download before you
login to avoid potential issues
During the stress test, lag and connection issues may occur
Please do not change languages in-game. This functionality is not
working correctly yet and will cause the client to crash
This is an open stress test – not a demo and certainly not a finished
product. You may experience a number of issues and errors, but this
is exactly what helps us to prepare for the smoothest launch possible

Try "spam-clicking" the start button. As in, clicking start, then hitting the enter key immediately after the error pops up; repeat. I can't say it is what the folks at Blizzard would want/recommend (can't find an official response), but it is what others seem to be doing with some degree of success. Possibly because the servers may able to support more players, but the login process maybe demands a bit more resources all at once, when compared to simply keeping you playing once already in-game?
It worked for me the one time, but this is my first time logging in after downloading all weekend. Good luck.
