I recently replaced my PC and tried to re-register Movie Studio Platinum 13 on my new computer, but I received the following message. Do you know what to do?
"Serial number already used."
The serial number you entered has already been used. You may have already registered. Registering again is not necessary. If you have any questions, please contact our technical support team at http://support.magix.net.
Hello Yoshi, you're on the wrong forum here. Could you please ask your question on the Vegas forum; there is a link at the bottom of this page. You could try Support, as it states, but you'll probably get a quicker answer on the Vegas forum.
It's the same answer for any Magix product - go to your Magix account https://www.magix.com/us/support/my-service-center/. Under My Products find your VMSP13 and deactivate existing activations. You should then be able to install but make sure you are using the same email address as your original installation.
If it doesn't work post on the Vegas forum as AAProds mentioned.
