Adding Remote Users

JohnK2CIB

My ham partner and I own jointly a 6500.  It was in use remotely on V1 software up until 2 years ago.  We are putting the remote station back together.  I have tested V3 software and remote access for myself successfully, but when he tries to connect from his home, where he has his own Flex6000, it asked him to sign in only once.  And when he brings up SSDR, it does not show his name and call.  It appears that his personal registration at Flex needs updating, but we can't find out where to do that.  Also, only his local radio is shown as a candidate for connection.  When he clicks on Smartlink, it looks at his local radio and wants him to purchase V2/3 for it. How do we associate him with the remote radio for which V3 was purchased?
