I have seen a similar problem a few days ago (http://forums.adobe.com/thread/621162), to which I replied, but received no feedback.
You don't mention your OS, but assuming that you are on Windows:
As I mentioned in my reply to the earlier topic, the Microsoft Fixit Center software is still beta, so I recommend a backup or System Restore Point before using it.
