When you encounter a problem with Audition, the following steps are often useful for getting past the problem and/or determining the cause of the problem:
1. Hold down SHIFT while you launch Audition
This overrides the preference files and launches Audition using the default settings.
2. Manually rename or delete the preferences folder
Step 1 only overrides certain preference files, while others such as Workspace preference files, may be the cause of the problem. Depending on your OS, locate the "5.0" folder in the location below and rename it or delete it.
Windows XP: C:\Document and Settings\<username>\Application Data\Adobe\Audition\5.0\
Windows Vista/7: C:\Users\<username>\AppData\Roaming\Adobe\Audition\5.0\ *
Mac OS X: ~\Library\Preferences\Adobe\Audition\5.0\ **
* "AppData" may be a hidden folder. You can type it into the location bar, or enable "Show Hidden Files" in Windows.
** This is your user-level Library folder, not the system-level tree.
3. Check your Audition Log.txt file
To enable a log file with CS 5.5, you must create an empty file in your preferences folder called "Audition Log.txt" using notepad, text edit, or any other editor. After you create this file, launch Audition and if it fails, open and/or share the log file for more specific information about what's happening.
4. Check the Operating System console or error log
Both OS X and Windows can track application errors, and if the problem is occurring outside of the application code - a driver conflict, for example - then the OS error report may be more informative than what we can get from the application.
OS X: launch /Applications/Utilities/Console.app Clear the view, then launch Audition and note any error messages that appear.
Windows: launch Control Panel > Administrative Tools > Event Viewer > Windows Logs > Application then launch Audition and note any error messages that appear.
5. Re-install Audition
If at this point, nothing has resolved the issue or the error logs are inconclusive, it's a good time to uninstall Audition, reboot, and reinstall Audition.
6. Obtain the full crash dump and send it to the Adobe team
So you've walked through all the above steps, you've disconnected any external hardware interfaces to rule out any device or driver conflicts, and you've exhausted the basic troubleshooting steps. Visit http://forums.adobe.com/thread/900619 and follow the steps for your OS that Charles has documented to best obtain a full crash memory dump for Audition, and send that to firstname.lastname@example.org with a description of the problem and the steps you've taken, and we'll take a look.
