I just bought a new OEM Sony Movie Studio Platinum 12 disc. It installs fine but Sony no longer accepts registration of this version, so, my serial number is not activated. I can choose 'register later' but get the prompt to register every time I open the program. Is there a registry edit I can do to prevent prompts for registering this product? I'm afraid after so many 'starts' of this software, it will cease to work. I feel like I'm in 'trial mode'. My OS is Win 7 Pro. Thanks. Ken.
