recover my song in 2018

[mikeyman]

hello I am confused at how to go about this..I have both new PT's 2018 and old PT's 10 computers running now but I guess PT's will only work on one ilok at a time.In my old computer audio drive I have ''session back up files'' and then I have my songs listed and it says PT's sessions.I have tried to send them to my off computer drive and reload them into PT's 2018 computer.None of them seem to have the audio files.Do I need to send the PT's authorization back to my old ilok back and try and bring up the songs in PT's 10 and save them in a different way.I thought PT's was saving everything to the audio drive everytime I close and save a session..Thanks
