FTP - "Root element is missing"

After some problems with remote FTP and disk quota on login user, I started receiving some errors "Root element is missing" on the send port, but the send port was set to pass through...

I stopped the orchestration and send port, sat sent pipeline to xml and apply. And back to pass though and apply. Started the ports and orchestration and I works again ;-)

Build hangs

Suddenly I had a problem with build from Visual Studio. It hangs!

But If I hide or close the "output" window during builds - its working - but why?!?!?!
