The Problem : Method not found (FCPublish).

Hi All.

When I push "Start" on FME2, The Following log is out on FMS2 LiveLog.

Sending error message: Method not found (releaseStream).
Sending error message: Method not found (FCPublish).

I make sure that "CONNECT" is successful.
And, I searched about this ,so I know that "releaseStream" and "FCPublish" is called by FME.

But, What should I do?
Can I ask your advice on something?

thanks.
