I had to format my computer, and did not deactivate the Datacad 18. Now when trying to activate the Datacad 18, I get an error.
go to the online license service

login with your dcad login, licenses Activations, pick the 18 license, manage it, hit the red "X" to deactive the old, then go back and start 18 again on your computer, and use your login again.
