@Alejandro-Lopez, you can use the same TRIGGERcmd account, but if you don't have the commands.json file from your c:\Users\(username)\.TRIGGERcmdData folder, you'll need to recreate your commands because that's where they were stored. For security reasons, they're not stored in the cloud.

You'll need to delete your old computer from your account because unless you're subscribed you can only have 1 computer.
