Hi, after formatting my Sony Vaio, I can no longer use the software pre-installed by the Notebook manufacturer because the Sony site for online product registration no longer exists. I need the authentication code for Sound Forge Audio Studio 10.0 and Movie Studio Platinum 12.0, but when I try to register on the Magix site, I get an error message explaining that the product serial number is already registered under another user's name . I have already wasted a lot of time, can you help me?
