Mac: upgrade to "aerofly Expansion Pack 2" not possible

Hello community,

I already updated my aerofly RC 10 to Expansion Pack 1 on my Mac some months ago. Now I wanted to urgrade to Expansion Pack 2 but I do not find the option in aerofly anymore. In the extensions section (Erweiterungen), I see the already installed Expansion Pack 1 but no option to add Expansion Pack 2.

Any hints for this issue?

Thank you and Best Regards, Thomas

... everything OK, after a Mac reboot I could by the Expansion Pack 2
