Yes, all character information was lost. You can recover your old accounts by asking for help here: https://www.warmane.com/account/support
You may make a new account to make a support ticket there if necessary.
Keep in mind, this will not recover your characters, but you may be granted some coins and points to start with on pre-existing accounts.
