In a late night flurry of activity, I intended to preview available widgets through the manager at Adobe Exchange, and I somehow disabled an extension while using Adobe Extension Manager. I could not find a way to enable either one. Enable column shows unchecked, and will not accept input, leaving no other (to my knowledge) option other than install.
On reinstall, it automatically disables again.
I then "Removed" the (2) extensions, and re-installed both, but, both were subsequently "disabled".
