@Mariana-Castro, if you didn't save your c:\Users\(your user)\.TRIGGERcmdData\commands.json from your previous Windows load, you've lost your commands.. You should delete your computer from your TRIGGERcmd account so you can recreate it from your new Windows load.
For security reasons, TRIGGERcmd does not store the actual commands in the cloud - they only exist on your computer in your commands.json file.
