Upgrading Showgun

Hello I have a problem with the program echo. Whenever I try to update the firmware of showgun occur an error that says "error: no fixtures ready for code".
I'm using the last version of echo, my OS is Vista, the current version in showguns is 1.0.8 and the update is 1.1.11, and i´m using the USB upload dongle.
Can someone help me.
