I could connect the Pscan to the toughbook and internet using a battery and the Mems 1.6 cable if that helps
Yes that would work.
I can find nothing in common with your toughbook and anything that the pscan has see before.
One possibility is that it has a switch to turn wifi or bluetooth off and when you registered it the switch was on and now it's off.
If there is such a switch then turn it on.
failing that:-
If you can get the toughbook on the Internet and connected to the pscan (green light flashing) then you are safe to "permanently remove" one or other of the PCs that it is telling you to.
Then try both the PCs (connected to the internet and to the pscan).
If either of them fail then I will be able to do something about it as there is a way to recover the situation over the internet.
