i only see one rig with this email.
Did you check this second rig pendrive that you have set email to yours ?
Can you boot it with lcd screen connected and see whats happening?
I am almost sure that you dont have set email on the second pendrive ? (meaby i am wrong)
Send me screenshot to PM when this rig will boot and first window top-left when it says "suffesfull registered on simplemining, login using email: ....."
