Image Artist: Why is the "Columbus navigator service cannot be found" error shown in the Image Import/Columbus Navigator interface?

Problem: When attempting to use the Image Import/Columbus Navigator App (within Spotfire) to download results files from a Image Artist server, the following error is displayed in the Image Import/Columbus Navigator interface:

"Columbus navigator service cannot be found, please contact with administrator."

Cause: The server URL used during the Columbus Navigator Login included a trailing backslash.
 

Solution: Remove the trailing backslash from the server URL during login.
