Updated my Internet Security 10 to the latest. Put in the Serial Number and it won't accept it. Called Best Buy and they tell me I have to add the dashes in the Serial number or it won't work. I told them there is no way to add dashes since inputting the serial number is in 5 boxes with no dashes. They say they will transfer me and then nothing. You don't support your software and Best Buy blows me off. How do I get my money back so I can get software to protect my computer.
