There is no problem with your game or computer at all, it's just how it works and sometimes that "Glitch" happens.
Sadly, you just have to keep trying until you can get in, from my experience.
I really hope that doesn't deter you from the game, it's really a great place when it's up and working properly. ^^
Also, I haven't heard about any fixes for it yet. But, there might be one out there somewhere! Maybe try youtube?
I hope you have fun in-game,
