Cant use the login on google +

[Hummer]

Hey STS

Yesterday when I tried to log in to my account, I couldnt get it to work (I use Google +).
I cant press the "login & play" button as seen below on the picture, and I have no idea why. Also first time this has happened.
Any suggestions on how to fix this?

Edit: I cant log on with the STS email option, so it seems that google + is the problem.
