I have a serial number, as shown in my Magix account for the Vegas Edit Pro 13, and I tried to activate on a new install of VGP 13, the "trial" version keeps coming up, asking me to enter the serial number, and accepted it, then the sw says it will restart, which it does and still returns me back to the trial screen to enter the serial number again. I also tried to activate on the Magix service center, but I have no idea what I should put into the "Computer ID" field. I trried a MAC Address, and computer name, but neither worked. I can't find anyway to contact Magix.
