Accidentally deleted 'accounts' folder from letsencrypt directory

Hi,

I’m using following letsencrypt packages:

root@host:~# pip show letsencrypt
Name: letsencrypt
Version: 0.7.0
Summary: ACME client
Home-page: https://github.com/letsencrypt/letsencrypt
Author: Certbot Project
Author-email: client-dev@letsencrypt.org
License: Apache License 2.0
Location: /usr/local/lib/python2.7/dist-packages
Requires: certbot
root@host~:# pip show certbot
Name: certbot
Version: 0.13.0
Summary: ACME client
Home-page: https://github.com/letsencrypt/letsencrypt
Author: Certbot Project
Author-email: client-dev@letsencrypt.org
License: Apache License 2.0
Location: /usr/local/lib/python2.7/dist-packages
Requires: zope.interface, pyrfc3339, setuptools, cryptography, zope.component, pytz, ConfigArgParse, configobj, six, PyOpenSSL, argparse, acme, mock, parsedatetime

About archive. I’ve restored all keys and certificates. I’ve used @Osiris advice from this topic: Restore pem files
I downloaded all certificates form https://crt.sh and compared it with keys from keys/ directory. Keys matched all certificates. Currently my web-site is running.

Now I want to restore accounts (with advice you gave me) but still worrying if it’ll work.
I have letsencrypt repo on another node for another web-site and there is no any damaged folders. Maybe it can help me to restore accounts on current node?

Many thanks
