Thanks Overcool for the response. 

Ya, I'm missing something.

I have the following in setup config.

My_Rig="auto"
My_Address="0x68BC2D6914B2EDF33495063B74a6D99cBB5945DB"

I still get the same error

Invalid argument: 0x68BC2D6914B2EDF33495063B74a6D99cBB5945DB.2FE64R

I see the "Auto" did change the rig  name at the end of the string, but it still bangs out with Invalid Argument.  I've tried 3 different ETH wallet addresses in the address line, and while the string changes to reflect the value change, I still get Invalid Argument.  Any ideas?

Thanks a million,
