Game loads with wrong language

[bob]

So, after some digging it appears that the language is configured in Battle.net, and this sets some cache value on the Battle.net Agent, and when you launch D3, if it is not already running, it starts up an Agent, and requests the locale from it. So, you need to log into each battle.net account, and change the setting in Battle.net.

If the languages don't show for you, then that is a different problem which points at some corruption somewhere, and would need to be sorted somehow. Maybe by doing a Scan and Repair, or
you could also try the Reset In Game Options for each of the Battle.Net accounts.

If it comes down to it, maybe a game reinstall?

So my problem is finaly over.
