@ken4, launch Xcode and check the provisioning profiles listed under Windows > Organizer. It’s the very first in the Organizer window under LIBRARY section. You’ll see all the provisioning profiles, and you should just delete/remove the ones that are no longer valid. And then, relaunch Corona Simulator. Once removed from Xcode, the invalid provisioning profiles should not appear in the drop-down when generating a build. If you don’t see any provisioning profiles, click on Refresh at the lower right corner, which will import all of your provisioning profiles for you, and then you can isolate and remove the ones you don’t want.
Edit: By the way, you can rename the provisioning profiles at Apple Dev center. Once you rename it to more recognizable names, you shouldn’t have any trouble selecting the one you want to use.
@nate2, I’m not very sure why it’s happening to you, but just in case… are you using the latest version of Xcode? I don’t remember exactly when the Xcode upgrade requirement took place in relative to Corona builds, but I remember at some point this year, the Xcode update was necessary to build for more recent version(s) of iOS. I believe it was Apple’s mandate. My Xcode version is 4.5 and I have no issue generating device builds.
Edit: @nate2, I’m now wondering if you are having the very same problem kurtbieg is having. Please see his post here (and ensuing posts). Sounds like a nightmare (just like the one I had with renewing my certificate yesterday):
