HW Remastered MP Beta Cannot "click" the button

This is going to be a brief topic but I was having a problem trying to play MP. I can open the game no problem, but when I’m on the main menu, I cannot click “Multiplayer - Beta” for some reason. I would wait a bit but nothing happens. It worked last week before I switched my ISP so their might be a probability that that is the reason.

Thanks.
