I have a brand new Sony turntable and Sound Forge Audio Studio LE. It is several years old but I have never taken the time to try to make it work so I can digitize my vinyl. Now, I have to register it to activate it. The website tells me that my serial number is invalid. I have tried everything, I have spent hours on this. What do I do? I just want to make it work. I need an activation code, right?
