it's only after i uninstalled nod32 from my computer the problem is gone. You can also refer to this thread on our Local forum. http://www.thinkdigit.com/forum/showthread.php?t=107906
Hello, now i think the problem is something else, I found that when i used a different ISP (Tata Indicom) HSPA usb data card connection than my previous one SIFY (ISP), the problem was gone even with Nod32 installed. I am confused. Anyway i tried on both 3.0.642 and 669 trials.
Thank you for the update. Let us know if the issue comes back. Otherwise, it looks like you found the cause.
