If it keeps going inactive sounds like there may be a problem with the Add In.
Maybe they have seen the problem before. This is from the Adobe Forum
If the above solution doesn't work, try the following:
- Click the Office PowerPoint button (upper left), and then click PowerPoint Options.
- Select Add-Ins. In the Manage pop-up menu at the bottom of the dialog box, select COM Add-Ins and click Go.
- Select Adobe Presenter Powerpoint COM Addin from the list. Write down the Location path.
- Deselect all add-ins in the list except the Adobe Presenter Addin and click Remove.
- Click Add and navigate to the MenuLauncher.dll file at the location you wrote down in step 3.
- Click OK. Click OK again.
