Problem with setting up ColdFusion within Flash builder 4.5

I new to ColdFusion and I trying to connect a Flex App to Coldfusion. Thanks to Adobe Tutorials I have successfully installed Coldfusion and it works perfectly with Coldfusion builder. Unlike other Flex developers I didnot install the Standalone version of ColdFusion, which makes the Integration part with Flash Builder very difficult. I do not want to reinstall ColdFusion again, because everything else works just fine. Below I have attached a Screenshot of the Server settings ioin Flash Builder (and the error message).

My question is: Can Anyone show me how to do set it up properly??

thank you

Ps: Hope you understood my problem
