Trying to connect to X6 CODA from Qt Creator 2.3.0

Hi
I am trying to connect to my X6 Nokia from Qt Creator 2.3.0. I open the CODA by navigating on the phone to RnD Tools, then select Public CODA and open. A screen appears that says:
[COLOR="purple"][INDENT]"Welcome to CODA for Symbian OS
Status: Connected
Connection: USB
Port: 0"[/INDENT][/COLOR]
But when I want to Run the app on the Device from Qt Creator, I keep on running into this problem. Have not been able to make this work even once!.:confused:
