Error encountered while starting Boxifier service: 29

I have a Server 2012 running Boxifier. It had been working well, but after a restart just now, it seems to be having trouble starting the Boxifier service. See error message below:

Does it make any difference if you download and run the latest Boxifier installer on top of the existing installation?

I got it working then.
What happened was that the password for the admin account on the domain this server is a member of was changed. I was digging around under Services and saw that the Boxifier service runs as the admin user, so I updated the saved credentials under the settings for the Boxifier service in the Services administration application.
