If you don’t remember which HMP licence is tied to which MAC Address or HMP Interface board, perhaps this will help:
You can open the .lic file in a text editor and look for the HOSTID= line. If the file names contains _host_ then it is locked to a MAC address which is listed as the HOSTID (ignore the first digit, the remainder is the MAC). If it’s the license file contains _heb_ in the name, then it is locked to a board, but the serial number of the board won’t display in the file. You’d have to send us the delivery link for that license so we can have someone find out which serial number is associated with it.
