Domains Disappear in Plesk

[arazas]

More than 130 domains disappear from Plesk and all belongs to client "ABC". The accounts are available physically on server because we have account available c:\inetpub\vhosts\ physically, all data is safe and same for emails, databases but all stuff is missing in Plesk itself. No one else have access of server either Plesk or RDP. I solely knows the password.

I tried to run Plesk reconfigurator to validate Plesk databases but still it is same.

Please help we are in big trouble as we can not manage the accounts.
