@Mark-Hollis, your commands are not stored in the cloud. They're only stored on your computer, so if you don't have a backup of your commands.json file, you'll need to recreate them. One Windows you can find your commands.json file in this folder:
c:\Users\(your user)\.TRIGGERcmdData
If you're not subscribed, you'll need to delete your current computer before you can create another one.
