I bought the Vegas Movie Studio 17 Platinum and I was able to register the other elements (Movie Studio Platinum & Music Maker) using my serial number. However, when I go to activate and register the Sound Forge Audio Studio 14 using the exact same serial number and method, I get error code 14 which says 'The serial number you entered is invalid or may apply to another product'. I'm using a PC computer. Any help on this issue would be much appreciated.
