tired of "where is the debugger or host application"

[ralp...@googlemail.com]

Hi guys,
I am trying to debug flex/as project in Flex Builder 3,
everytime I get the following message (even when I pick run, not
debug):

I am so tired of this message...

"where is the debugger or host application running?"
*Localhost
*Other Machine
Enter IP adress:
Connect/Don't Connect

I did one heluva googling on this one and still can't solve it.

1. I did uninstall all flash players on my machine.
2. I did download the flash player 10:
http://www.adobe.com/support/flashplayer/downloads.html
Download the Adobe Flash Player 10 Update for Windows and Macintosh
(ZIP, 41.8 MB)
3. I went to the Debug folder, then installed the file "Install Flash
Player 10 Plugin.exe" - for FF.
4. Still it pops out every freakin time I preview my .swf in a browser
locally.
"where is the debugger or host application running"
"where is the debugger or host application running"
5. Installed newest Java Runtime
6. I turned off the whole windows firewall/defender system and still
nothing

Also I've read here that it is most probably an issue with
communication between .swf and flex builder debugger,
but I did turned off the windows firewall so It should be ok?

Or meybe there is some workflow required to mate .swf with flex
builder?

Cheers
