Ahhhh! Yeah I had trouble getting in a few months ago.... And honestly I don't remember how I got in I think I asked around here but can't find that conversation.
Some troubleshoots are restarting it, un/reinstalling, running as administrator... Uhmm.... Disabling your firewall? Idk. One thing, once you get in and can play the games, DON'T LEAVE THE PAGE because it will glitch.
