Can't login to admin – hosting and email address company gone

Hello,

The company that I was getting my hosting, my web address and my email address through has gone under very suddenly. I decided to let account just die out rather than switching to another company, because I had been ignoring not-yet-launched site for so long I was starting to wonder if I should continue with it.

I eventually decided to give it a shot, and tried to login, but found out that I was unable to do so. I realized that my login username was my now-deleted email address that disappeared with my hosting company. I don’t know if it is possible to receive a password/username reset, or what options I have to login, but any advice is helpful.

I didn’t have a lot of the site set up yet, so I am happy to start over. However, it would be preferable to just be able to go back in and continue from where I left off (even if it was just a little progress).

Hoping you can help.
Cheers.
