Do not install! Locked out

Installed it and afterwards I got logged out of the website and could not login. Had to manually input admin username and password in the database to recover website.
Was able to decrypt part of the user data afterwards but addresses remained encrypted.
If you do not want to get a headache, do not install! Should be removed from the repository.
Called the developer. told me to send an email and he will tell me how to recover the data, aftee that, he did not answer any more calls or emails.
