This error message was not generated by Windows, it was generated by the Python Library, so something is wrong with the Python scripts.
The IP 127.0.0.1 is not an internet IP, the internet is not used. This IP is the IP of the local server.
Windows firewall doesn't block the local host, it blocks only messages coming from outside the computer and never from inside, so it is useless as firewall and protect you nothing, so you can disable the firewall and install some other that really works.
The error message tells that the remote procedure call (RPC) returns an error message, something is wrong with Python. Maybe some other application has installed a Python Library too and is interfering with Poser's Python or Windows is screwing all Pythons.
If re-installing Poser solves nothing it means that some other application is not compatible with Poser or Poser is not compatible with some other application.

Stupidity also evolves!
