umm, you can add that to the profit profile specifically for sgminer (and forks)
also, you need to specify the correct number, 0, 1 or 2 for the --gpu-platform, it's rig specific.
check sgminer --help for details.

worst come to worst, just use command line and mine to someone else's address using examples for starters, there you should see all the error messages in the console. of course, if you are familiar with command line, then just replace the command, addresses as you see fit. Else, consider it a tiny donation.
Was trying to set it for the Managed Software but it would not take. Going into each device profile and having to add it is not ideal, but can work for now.
It runs, but still does not coy the benchmark result back to the test page for saving to the profile. Hum ...
Thank you.
