launcher isn't working

Connection is normal. But once I enter my account name / password / security token, the button doesn't want to launch. No maintenance or any issue, the worlds are up and so is my connection like previously stated. I can click on the red button but it just won't do any action after I click on it. So obviously I can't log in and it's kind of frustrating...
I tried to turn off / on my pc hoping it will solve the issue but it doesn't. After a couple tries I gave up then couple hours later it will work like it should. The issue started after the maintenance.
