Update really impotmant

Hello, I’m having a problem with Umbrel on my HP computer with an Intel Core i5. I wanted to download the new version, but accidentally reloaded the page during the “Restarting” step. Since then, I haven’t been able to access the site. I’d like to reinstall Umbrel, but only if I can still recover my data. If possible, please feel free to contact me in German.
