Recovery from ethereumwallet.com?

I was clearing out old entries in my password manager, and i came across an entry for ethereumwallet.com. Just in case, i figured I'd check if there was anything in it. However, apparently the website is long since defunct. I've looked for guides on recovery, but they're all old and dependent on another piece of defunct software, or a web archive page that isn't working for me. I wanted to check if there was anyone else who had managed to recover the data, or could give me some guidance. Thank you!
