I had purchased AVG antivirus two days back. I installed it. But it is not getting activated. I got licence number through email. I typed the license number on the given space and clicked 'Activate'. But nothing is happening. I waited for so long and repeated the same so many times. No any error messages too. The validity of this DVD is one year. What should I do to get it activate?
