Flex ColdFusion connection issue with AIR app

I h开发者_运维知识库ave a smoothly running web Flex app which interacts with a database via ColdFusion. However, when I try and adapt it for AIR I get this error:

Send failed
Channel.Connect.Failed error NetConnection.Call.BadVersion: : url: 'http://iki_Lyric_Air.swf/flex2gateway/'

I am running it locally and the swf should be iki_Lyric_Air.swf. I tried changing/shortening the name of the project but the first letter was still omitted.

Any idea what is wrong?

Usually the URL is of the type http://[server IP]/flex2gateway/. Please check the URL that your services or Remote Calls are pointing to.
