I had experienced one time, but able to solve this problem end of the day.
When click on debug and start the download progress bar shows progress and Carbide displays “Carbide Alert”: “Load Failed”, “TRKProtocolPlugin: Unable to download file” (as shown in the picture below).

Solution:

• Right click the project from “Symbian Project Navigator” panel, select “Properties” -> In the “Properties” dialog, from the left tree panel, select “Carbide C++” then “Build Configurations” -> In the “SIS Builder” tab, make sure build for myapplication.sisx is checked, and “Partial Upgrade” is also checked.

• If you don’t see the symbian_ua.sisx entry in the list:
Press “Add” -> set “PKG File:” to C:/…/sis/myapplication.pkg -> if you have certificate and key than select “Signing Options” otherwise select “Self sign sis file” -> press “OK”

• Right click the project from “Symbian Project Navigator” panel, select “Debug As” -> select “Debug Configuration” -> In “Debug Configuration” dialog, from left panel, select “Symbian OS Application TRK” -> do double click on this option or press new button to create configuration -> In “Debug Configuration” dialog, from right panel, see “Use connection box” -> Press on new for new connection and make new connection.

See picture below and be sure that you select correct option.
