Hi Hugo, 

Thanks for reaching out to Jotform Support. Our Spanish Support agents are busy helping other Jotform users right now, so I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, it might take a while until they're available again.

Now, coming back to your question, I checked your account, and there are no forms in it. The form URL you mentioned belongs to another user, and they have disabled it. You can easily clone the form using its URL. Cloning a form via URL is straightforward. Let me guide you through the process:

1. On your My Forms page, tap on the orange Create Form button on the top-left side of the screen, and tap on Import Form.
2. In the next window, tap on From a Web Page and paste the form link.
3. Now, tap on Create Form and you're done.

Reach out again if you have any more questions.
