Game launches into the log-in screen and a dialog box says that there's an update to install, so quits and takes me back to the launcher. However, the launcher says that the game is up-to-date. If I click play it then takes me back to the log in screen which says that there's an update available, and so on ad infinitum.
Any ideas?
Running Arch x64.

Got the same problem

Tried to install using both EU and US installers from scratch (I'm in EU) and even copied the whole installation from windows partition (it works without problems in windows), always the same problem happens.

Well, probably doesn't help you much, but it's working for me right now.

But I did have this problem before, and it was when patches hit - while EU servers were down I tried to login into US ones and I got the "need to update the game" but when I clicked okay and it went back to launcher, it said my game is up to date.
My guess is it happened because US was already on 1.2a (or whatever) and EU was still updating - and since I had an EU account/launcher, I didn't get the update yet.

Is it working now?

Also, I remembered seeing something on the US D3 forums, so I dug it up.

You could try this http://us.battle.net/d3/en/forum/topic/5235402919#15

And there is an extra thread dedicated to problems on updates it seems: http://us.battle.net/d3/en/forum/topic/5152415037

Hope it helps!

I've gone through logfiles and finally found what was amiss.
I was missing lib32-libldap library, after installing it Diablo 3 works!

Yay, installed lib32-libldap and now it runs perfectly. Thanks!

The problem is here again. Can you tell me how to install lib32-libldap ?
Thanks

aurelienbis: depends on your OS, but there is likely a lib32-libldap package... What are you using?

Mine is doing the same thing, runs game just fine, go to login then says there is a patch available and exits immediately back to the launcher. Launcher says that it is up to date, but same thing keeps happening... I'm running Ubuntu 12.04 LTS (Precise Pangolin)

In fact, it is the same thing at every patch update. We are doing update on US server, and his maintenance is one day before EUR. So for one day we can only play on US server.
