The disc is more than likely knackered. Have you had it from new? It was released in February 2004 so the disc may well have degraded by now. Are you able to explore it?

Fantastic the update is working though the process is a little more fiddly.
So you have to be sitting inside the cockpit of your Carenado aircraft in MSFS2020.
Open up the import aircraft page in Airhauler 2 MSFS and select the Import via Simconnect tab. Then press ok and then transfer the aircraft data to Airhauler.
Thanks devs.
