Well, nevermind that previous post.
Remembering some initial install issues with SH3, I decided to pop the disks in my DVD burner tray and now they're installing like a gem. Computers are odd things, no?
See you in the skies!
Edit: Any of you all with 1946....is there supposed to be a F4 Corsair on the title screen? Did this just install PF or is Sturmovik on there too?
