The UI Builder is very unstable. It has been my experience over the last few weeks that every few days it’s ceases to work (start it and it terminates). This requires a complete re-install of Airplay SDK (very time consuming factoring in all of the Apple certificate setup). Could you folks PLEASE supply a Stand-Alone UI Builder installer. As long as it is going to completely blow up every few days, at least I won’t have to re-install and setup up EVERYTHING!
