Unfortunately the last login to the account panel (x10hosting.com/sso/login) is showing as being on 1-28; if an account isn't logged into for 30 days, the account is issued an inactivity suspension and an email sent to advise of this. If the suspension isn't removed within 21 days, the account then terminates; this looks to be what occurred, as on 3-23 the account was terminated due to an unremoved/unresolved inactivity suspension.
Given the termination, the best we can advise is to recreate the account and upload from a local backup, as once the account was terminated all data on it was purged, and we unfortunately do not have a way to restore the prior account's contents.
