Unable to register Air Xpand!2 due to duplicate serial code

I installed and registered Air Xpand!2(PC) on 01/22/2019. The product Serial is BA1806161701257. However, I just upgraded to a new PC and installed a new copy of Windows 10. Now I can't register with my serial code because it recognizes it as a duplicate that has been registered previously on a different machine. What can I do?
