But when I try to register it Magix says that serial number has already been registered. I went on Magix site and entered the serial# to get authentication and it says it needs to be registered.

Recheck your spelling for Sony Vegas Pro 13.0 just in case, you might also want to try searching without the version number. excluding words such as these will result in much more accurate results.

When searching for Sony Vegas Pro 13.0 do not include words such as serial, number, key, license, code, torrent, etc. Well I don't think it's someone authorized, because a person online sold it to me, he gave me his serial number at a cheap price and I registered it in my magix account and I registered without problems and downloaded the program and installed and activated it. Sony vegas pro 13 serial number and authentication code 2017 Thank yound if it is necessary to have that authentication code or not?

Who do i contact to obtain the authentication code? Thanks The forms on SCS keep rerouting me to MAGIX. If it is not in your account, then you have not registered it. If youve registered the software, its serial number will be listed there. Otherwise, you can just go to the My Account link at the top of this screen and select My Software. All of the "forms" i have filled out on support keep redriecting me to MAGIX, but the pages fail to load as if their systems don't work or something. If you bought the boxed set, its on the inside of the box.
