Cannot connect to VM -> Mac OS X

[seagull1]

Hello,

I have just started to used GWT. I was running though the tutorial and
asked to debug the project for the first time (the stock ticker demo)
I got a message saying:

'Launching Stock' has encountered a problem.

Cannnot connect to VM

clicking on the message gives

I have tried Googeling for solutions but have not found any that have
helped.

All help is greatly appreciated.

Thank you
