Hello,
I purchased Studio One Artist as a trial, registered and downloaded it. I decided to buy the upgrade Studio One Professional, so I bought it, received the activation key, and put it into the Studio One Activation dialogue box as an upgrade key. However, there's an error, and I keep receiving a message that reads 'This Key has already been registered.' It hasn't. I purchased the upgrade and I would like to use it. Please help.
