This just started happening a couple days or so ago - I think it coincided with the recent update but I'm not completely sure.
I click Play on the launcher once, and it appears to start launching the game - but there is no sound on any of the logo screens until it gets to the login screen. When I put in the password and click login (or whatever the button says) it pops up a box saying a validation email has been sent. If I don't click on anything for a couple of seconds, the game exits back to the desktop but immediately starts loading as normal with sound on the logo screens all the way to login, which now operates normally.
