.app file appears in red (missing) in new projects with Xcode 4
I just upgraded to XCODE 4.1, upgraded to OS Lion, had to replace my expired developer and distribution and team certificates. Now my Product AppName.app appears red. The app compiles file with no errors using Base SDK IOS 4.3 and tests fine in the simulator and on the iPhone device. I've used Product>Clean, rebuilt it many times but the AppName.app remains red. Any help is appreciated. lq
