If you are still getting conflict errors, it means that either the configwizard wasn't rerun on the client computers, or the license folders on the other two computers weren't removed, so the config wizard got the same sequence assignment as before.
In order to get conflict errors there must be Pro admin server software installed on more than one computer, or, there was once more than one server, and not all the client computer had config wizard rerun to get a new sequence number.
When config wizard is run on each client computer it gets assigned the next available sequence number--in this case sequence number 1,2,& 3 will be assigned to the computer in order in which config wizard was run. But if there are three servers, each computer will be assign sequence number 1, and conflicts will occur. The assignments will persist on the clienct computer until config wizard is run connecting to the right server.
