license missing

Hi, I buy halion sonic 1 with free upgrade to halion sonic 2 then buy an upgrade to halion 5 . My halion sonic 2 license is missing. WHY?

The HS2 license is gone because you have upgraded the license from HS2 to H5. It is one license that has been upgraded, so it remains one license. A license of H5 can still open HS2, just be sure you have installed the latest eLCC from http://www.elicenser.net/en/latest_downloads.html
