I had been doing all of my Flash work via Adobe Flash CS3 and I have flash player 10 installed. I installed the flex 3 builder 2 month trial to get my fingers wet in OOP flash development. I’ve noticed that the trace() function is not recognized and when I go to Debug within Flex, I get an error telling me i cannot connect to the debugger.

Is the debugger not included with the trial? Is there a download or something to get it working? I saw an identical problem that someone posted on Adobe’s help forums dated in May but there was no reply from adobe.

Thanks for the help.
