it shows me waiting for your opponent i wait and wait an wait i waited for 30 mins then i cut and 3 points were deducted for walkover....................................................plz help............................................................

This happen rarely, be careful next time. But as you said you waited for 30mins and you got 3 points deducted for quitting is quite impossible because if you waited for 30 minutes, the game would be unreported.

Maybe you lost connection to the internet suring that time and you were cut from connecting to another game?

Do You use wireless? If yes maybe you lost connection look at the top of your window if the game freeze it shows a disconnected cable... and look at your network status if on wireless it may show a red cross going through it or a yellow light...
