Is this specific to a particular presentation ?
If not, which OS version are ypu using ? Is Presenter 32 bit or 64 bit?

I am having the same issue. I am running Adobe Presenter v9.0 on Windows 7 64 bit.
As am I, Adobe Presenter V9.0, Windows 8 64 bit, PowerPoint 2010.
Am having same problem. Checked in PowerPint Options/Add-Ins, and it listed the Adobe Presenter PowerPoint COM Addin's location as C:\Program Files (x86)\Adobe\Adobe Presenter 8\MenuLauncher.dll. This suggests I'm actually running Presenter 8. Am I reading this correctly?
Same thing is happening to me. One day it just stopped working. 64 bit version, Windows 7, PowerPoint 2007. All presentations.
The problem seems to be with the flash player.
Could you please install the latest version of flash player and see with this resolves your problem.
