You need to press the right downwards button. I usually enter on Lobby and press downwards to go to the specific room. You can only enter after a specific number of posts, you are way past it at 70 LOL I think its 5... and you just enter. If you are in lobby ask if you have a problem. Its ok if you go through a specific room. I hope that helps and I hope to see you in chat...soon
