Articulate tab disappeared from Powerpoint after installing update

Hi there, 

 

I have Presenter '09. I ran the recent update, and the Articulate tab disappeared from Powerpoint 2010. 

I went here:

https://www.articulate.com/support/presenter-09/the-articulate-tab-on-the-powerpoint-ribbon-is-missing

But, when I check the check boxes and hit OK, they default back to unchecked when I start up Powerpoint again.

Any ideas to get Articulate working again?

 

Best,

 

Andre
