I cannot get Movie Edit Pro Plus to open. I downloaded a demo and tried to run it as a demo. It is asking me for a license number which is supposed to be sent to me when I register. However, when I click on Register, it doesn't do anything.
If the Registration screen is failing to contact the Magix servers (assuming they're not affected by the current worldwide cyberhack!) I would suggest you ensure your firewall is allowing MEP through. it doesn't do anything sounds very much as if the connection from your computer to Magix is being blocked. So, I think you should check your firewall settings.
