Lost History Master for list handling

[montana722]

Apparently in my attempt to download an update, I lost the History Master to edit and delete titles of documents I have opened. Is this a difficult or complicated problem to restore ? I can get along without it but it is useful to be able to modify the list and the number of titles in my most used list of documents.

I have attached a screeshot of the error message I get. Any help very appreciated.

Simply push the jigsaw icon near the bottom of your screenshot, download the missing extension and install it. You might have lost a lot more than that, probably because you did not shut down the office suite while updating.

I tried a search for what I think is the exact script but it shows zero results for that name.
