I am having the same issue. I have just purchased a Helix LT with version 2.6 firmware and downloaded HX Edit 3.11 and it wont let me update the firmware as the it will not let me create a backup. I keep getting an error message "Backup dialog failed to load". Cant even use the File/ Create Backup. I tried downloading HX edit onto another computer and that one is even worse and it wont even open HX Edit. I really want to backup & update so I can start loading in presets but cant. Can anyone hept with either of these 2 issues with HX Edit?
