When I press Shift+Ctrl+Enter, I get this message:
I used to be able to debug, around April 2011, but for many months I have not been able to.
I've search every thread on the internet regarding this problem and none of them have helped.
What could be causing this problem?
Are there any known software conflicts with Flash Professional?
If anyone can help resolve this, you will certainly win thousands of internets. I've been at this problem for months.
I had this same issue just this morning after updating from cs5 to cs5.5. I took a sort of shotgun torubleshooting approach to it, so I'm not sure what actual step did fix it but it did start working. I checked for updates through adobe help and updated(didn't fix it). I did the host thing as stated above, and restarted flash, didn't work. So i undid that. I then moved my cs5 fla file to a new folder only taking my images that were associated with it along too. I then cleared the debug log. I tried debuging and it worked. I think what really fixed it though was that I also go rid of the old debug xml file that gets created. When I moved to the new folder, I didn't take that file with me. It recreated when I tried debugging after the move. Hopefully this helps someone else that had this issue.
If you still have the files and the bad xml, can you please forward it to me? Please zip your files, change .zip extension to .zzz, and email the attachment to my attention at FlashAuthBetaBugs@adobe.com. I'll take a look.
Flash Pro, QE
If it's helpful to anyone, I encountered this issue after a power failure. The *-app.xml file that was generated for my AIR program had become corrupted. I deleted the file and re-published my app and everything worked from there.
