I use Vegas Movie Studio Suite 15.0 Platinum for a work PC. I have purchased the license for it and it states that it is good on two machines. I bought the product off of Amazon as a digital download and I don't have the activation code. Every three years we have to upgrade our work laptops. I recently have rolled over to a new machine and I am trying to activate the software on my new machine. I have gone to the Magix.com website and tried to generate a code by inputting the serial number to my active software, but it keeps giving me an error. Please Advise.
