It's good to see you here in the Community, @ADRIAN1992.
I want to ensure you can get an app that can help you reset a password and upgrade your backup file.
While I can't recommend a specific app to you as there are many great ones for you to choose from, you can visit our QuickBooks Desktop Apps Store website: https://desktop.apps.com/home.
Just in case you want to restore your file, you can check out this article for more guidance: Restore your file.
Come back to this post if you have other concerns or follow-up questions about this. I'm always here to help.
