HELP : AP100 v5.20

Hello I'm new here. Our computer hard drive broke down. So, we bought a replacement and re-install necessary softwares including AP100 v5.20 for our laser machine.
But, unfortunately upon registering the license using our (license.dat) file back up from the previous hard drive it prompts that the dongle was already registered to other PC.
We're using the same dongle used from the previous hard drive and only the hard drive was replaced. Is there any ways to register the software? Thank you!
