Need to re-enable Convert and Combine Acrobat commands

I had Acrobat crash the other day, and Directory Opus said it was disabling the Acrobat shell command or add-in or something. I can't remember exactly what it said, and I don't know how to re-enable those context menus. Can someone point me in the right direction?

Settings -> Preferences / Miscellaneous / Advanced: ignore_context_menus

It will probably only have one value in it (the one for the Acrobat menu), in which case you can just select it and click reset to clear it.

Thanks. I wouldn't have found that one easily.
