Can't add a server to the GUI

I just took over SQL Server DBA support at my company. I did a new install of the SQL Backup GUI tool on my desktop. It's version 4.2.0.425. When I try to add a server to the list, the dialog goes to the end and says that the serever is successfully added. When I hit the Finish button, the following error is generated and server is not added to the list...

This error occurs if I use standard or integrated SQL security.

Any answers?
