Thank you very much. I download 2.6(stable edition) from here 2.6 SL , and it is working. Note: in Beta viewer I disabled auto-update , it is saying a required game update must be installed.

Fixed..... Since the update 2.7 and up I am unable to lunch SL ; thus , I revert back to 2.6 Beta and when I tried to login it said"you must update the viewer to be able to login" i,e you don't have to login ....!
