Upgrade to Mountain Lion and LiveCode 5.5.1 Problem

[Colin Holgate]

I have seen the simulator timed out thing, and quitting the simulator and giving it another chance seemed to help.

Another thing that can cause such messages is if you have not given the app and Internal ID. Leaving at at the default text can stop the app from being installed. Enter something valid, like "com.rogerguay.appname", where "appname" would be the name of this app perhaps, with no spaces.
