There is the unanswered question of what version of NVDA, as well as what versions of the Add-Ons, are present.
System Restore (which I personally dislike because it's both unreliable and incomplete) only rolls back your system registry and certain folders, but not all of them. It is not, in any meaningful sense, a full restore but is, instead, a selective partial one. See the articles:
I'm in agreement with Mr. Vonderlinden that an complete uninstall of NVDA, and all associated add-ons, and a reinstall of same is the thing that is most likely to rectify the situation the most easily.
