Hi, I know there are tons of people with this problem and just as many websites trying to figure it out but I still can't figure out what's going on. I'm extremely new to iphone development (so I apologize if I've missed something stupid) and have tried everything that I can understand on the sites with no avail including scrapping everything and starting over, trying new profiles etc. Currently I have the Apple Worldwide Developer certificate installed to my keychain as well as an "Iphone Developer:Erin Rosenbaum" certificate (this shows a private key underneath it). I have one device registered in the portal (its an ipod touch running 2.2.1). I currently have one provisioning profile (composed of app id: AMIKeyboard 'bunchOfRandomCharacters'.*, then my certificate and my device) which is installed and xcode and on the device. When pressing Build&Go I get the error: "Code Sign error: Provisioning Profile 'bunchOfNumbersAndLetters' can't be found". In the build info for the project I've set the Code Signing Identity to "Any iPhone OS Device" and "Iphone Developer: Erin Rosenbaum (randomCharacters)" (which was the only option aside from "Don't code sign" and "other"). Any suggestions on how to fix this would be very appreciated. Thanks.
