I had a client come to me years ago who had done this same thing after a product launch and a heavy round of user registrations. I was able to reproduce a significant amount of registration data by parsing it out of the request logs generated by the framework they were using and the proxy in front of it. We were able to get usernames and email addresses, recreate the accounts and send an email asking everyone to reset their passwords.
You may be able to do something similar depending on your stack. Good Luck.

Never thought about using the log. Will try and see what I can salvage. At the very least I can email them individually.
Thanks!
