I have been previewing Movie Studio 16 Platinum and decided this morning to purchase. I made the purchase (Movie Studio Platinum 17) and, when I opened the software to enter the serial number, I was asked to register the software. I started to register but could not get the registration completed because i forgot my account password. I asked for a password reset, but, when I receive the reset email, the link doesn't work. I then used a different email address for a different computer that I also had the software installed on. I then received a message stating that the SN was not valid. When I went back with the first email address, I received an error stating that the software had already been registered using a different email address. I am at a loss as how to fix this. Any advice would be greatly appreciated.
