I used the Apple MigrationAssistant to switch to a new computer, and now MonoTouch does not start my application in the simulator because it says that my license is not valid. Following the instructions in other posts here, I deleted my license file and re-started the setup, but I was just told that everything was installed and the application was running with the same problem. So, I completely uninstalled MonoDevelop and restarted the setup. He dutifully downloaded MonoDevelop and installed it, but never gave me the opportunity to activate, so I was still stuck.
