Uninstall that program. Then reinstall it.
Something happened to my MS Works word processor. It works fine, but when I initiate it (click on wkswp.exe) i get the "unidentified publisher" box, and have to click on "ALLOW, I trust this program" to continue. I know MS is the publisher, but what happened to make th OS lose its I.D., and how can I get it back to normal? Spreadsheet, Database, Notepad, and Wordpad don't have the problem.
