Probably you have a bad installation of either Aurelius or Delphi.
Make sure you don't have duplicated units Aurelius.Json.Interfaces.dcu in your hard disk.
Review your paths in library path to see if they look correct and are not pointing to duplicated Aurelius.Json.Interfaces.pas or Aurelius.Json.Interfaces.dcu files.
Finally, I suggest you use TMS Smart Setup to install TMS BIZ files. If possible uninstall everything, delete all remaining files in disk and reinstall using TMS Smart Setup.
