License move failure

I am using Mathcad Release 15.0 and DatecodeM005 Invalid host I'm trying to move my old mathcad 15.0 license to my home computer. I get Flexnet licensing error -9,57. I've tried generating licenses with both the ethernet mac and the wifi mac. I tried putting the laptop on ethernet and verifying that port was active with the matching license file. Here are the errors that I faced Invalid Host... Feature: Mathcad Hostid: PTC_Hostid=40:c2:ba:fe:42:7b (this is the ethernet mac) Flexnet error:-9,57 etc.
