Missing attachments and Can not attached new docs

I am missing attachments that have recently been attached to contacts. Also I can not add any new attachments to any of my contacts. Does anyone know if

  1. This can be corrected?
    or
  2. Can I go back to the version I had before?

I think this may have to do with a new feature in eM Client that only displays fields that are supported by your server.

If your server does not support attachments in contacts, the field will not be displayed.
