I just bought Your package that includes MovieStudioPlatinum170, SOUND FORGE and Music Maker.
After downloading, installing everything and putting in my email and serial code, I successfully entered MovieStudio and it works fine. Same for Music Maker.
But when I enter SOUND FORGE, it again asks me for email/serial, which after I enter (and gets checked by green arrows so everything is fine) instead of opening the program it shows "Error code: -14 The serial you entered is invalid or may apply to another product."
