Ok, there is good news and bad news. The good news is that I understood the instructions and followed them, and now I no longer get the "Please insert correct CD" message anymore. The bad news is that now, when I click "Go to Hangar," nothing happens. I hear a voice that says, "Contact!" then, "Clear!" and an engine starting, but after that, the music just continues...
Any ideas? Thanks!
