Everything was working fine but I don't know why I cannot connect to the debugger anymore!
even if I create a simple AS3 project and hit Ctrl+Enter, the window and my project compiles fine and runs but the debuger does not connect! and it keeps saying "Waiting for flash player to connect to debugger"
I even disabled my firewall but the problem persists...
P.S everything is working just fine on my other computers
ooooh, please delete this post. it was my own silly mistake I had changed the ip address of my local computer and the debugger was not connecting to it I changed the debugger connection ip address and now it connects successfuly.
