I have installed Java in my laptop, I can log in but whenever I click the "play" button it doesn't give me a table. Does anyone know what's wrong? Thanks.

HMMM... I tried to put my laptop into your laptop's shoes...I deleted my CURRENT JAVA and download the one from this website and it allowed me to log in just fine.
CLICK HERE to see if it was the same place where you downloaded yours. If not try to uninstall your current JAVA completely and install with this one. If this doesn't solve the problem, then you should check your internet configuration.. you probably done it already, but simple things such as making sure your cookies is enable and you are not behind a firewall may prevent java from showing up. I hope this solve your problem and be able to play. Good luck!!
