Trace() not working?

Hello there.

I've been searching around on google for the better of 8 hours now, without finding an answer.

I'm sorry if it's been answered, but it seems I couldn't find it.

So, my problem:

After having played around with AIR for about a week or so without problem, I am suddenly unable to trace() things - I'm using external as (that is, *.as files). The application works fine (doing what it should do), but it's not tracing anything.

The "Omit trace" box is not ticked, and I don't have the debug player installed, so a mm.cfg file wouldn't do much (I also tried making the mm.cfg, and this traced to a logfile) - I want it to "live-trace", and not have to look at a log file every time I test my application.

It was working, but suddenly stopped working - from one test to the other. I tried opening some of my backups, but still nothing.

I've even tried making a new .fla with an accompanying .as file, with trace("Working") as the only thing written in the constructor, and the movie loads fine, but it doesn't trace anything.

Then I tried making a new .fla with internal actionscript, and again, it doesn't trace.

This problem doesn't occur if I, under Publish Settings, use Flash Player 10 as the "player". But as I'm using some AIR-only things, I have to use Adobe Air 2.

Thanks in advance.

Edit:

Some more information (and tl:dr):

Application/Movie is working, but trace is not();

Wishing to "livetrace" (having flash IDE trace), and not be forced to log to a file.

Using Adobe Flash Pro CS5, don't wish to change.

Not using Flex

Windows 7 32Bit

Latest Adobe AIR SDK (from get.adobe...)

Not using cmd to compile, using Flash IDE.

Don't want to use third party program to trace, I know the Flash IDE is capable of tracing.

Have tried both Ctrl+Enter as well as Ctrl+Shift+Enter (Although the debug mode, when closing the app, tells me that "Debugger launch failed")

Output Filter level set to Verbose.
