Since today the Emulator does not work. I have tried downloading the aistarter download from the website and reinstall.
It was working fine for the last week without any issue and problem started today.
I have also tried Hard Reset and Reset connection options but no luck. I uninstalled, reboot and installed ai setup and it all goes through ok but still does not work. The aistarter screen shows no activity. 
. It just stays that way. I can Ctrl-C to quit
