I've tried everything, firewalls, reinstalling etc etc. I can't get the debugger to connect no matter what I do.

I'm just writing a simple Air application, with Flex and Actionscript. But any type of debugging on any type of application doesn't work. I get this message

The Flash Builder debugger failed to connect to the running application.

Initial Error

Then often when I try again, I get this message

Unrecognized Windows Sockets error: 0: JVM_Bind

Secondary Error

Running the program without debugging works fine.

I believe this indicates that the tcp connection between ADL and Flash Builder could not be established using port 7935 because the socket is in use.

Use netstat to assure the port is not in use.
