Authentication issues

Hello,

Just bought and installed the game, but can’t get over first screen to launch it. Set up new account, verified e-mail address, battle net logs in OK to my account.

Please support

Glad I’m not the only one having authentication issues. I just thought I’d want to go and do some Arcade mode games after a long time, but anytime I try getting in, it doesn’t get past authentication and says there’s issues with it.
What’s going on??
