Error while releasing applications in to iPod

I am getting the error A signed resource has been added, modified, or deleted while releasing applications in to my iPod. previously by mistake i tried releasing the same application in to iPod but it didnt run as there was errors in 开发者_高级运维my application. After rectifying the errors when i tried releasing the app its showing the above mentioned error.. Pleasing can anyone help me..

Try to do a clean build (Cmd-Shift-K to clean all targets). If that does not work, look into a previous question on this topic.
