Cannot Restore Default Configuration

I have MBWE with Feature Pack Manager installed.  My brother made some changes on the configuration but messed up the SSH access. When I try to connect with PUTTY I get “Connection Refused” error.  So I backed up all the data on the drive and then Restored Default Configuration.  I logged with default " admin/admin "  and then made first time configuration. For my surprise the data on the drive was deleted but the configuration was the same.

Is there other way to Restore Default Configuration or fix the error with the SSH access.
