I have a similar issue on 3.1.3
Mac mini running 10.6.8
PC monitor app runs and validates but doesn't display on iphone.
Uninstalled and reinstalled and the app had to be force quit a few times to even start and once it did still no change.
Any suggestions please?
*update* the finder bar at the top of the screen where the icons, date & Time , wifi are the pc monitor icon now doesnt respond
