How to export an AAF file from Logic Pro 10

Everytime I ask the answer is always:

Export the current project as an AAF file

1. Choose File > Export > Project as AAF file (or use the Export Project as AAF File key command).
2. In the Save AAF File As dialog, choose the following pop-up menu options:
   • Sample Rate: Choose 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz.
   • Bit Depth: Choose either 16 or 24 bit.
   • File Format: Choose WAVE or AIFF.
   • Dither Type: Choose one of the dithering algorithms (see About dithering algorithms).
3. Choose a location, enter a name for the file, then click OK.The export includes all used regions, inclusive of track and position references, and volume automation.

But whenever I follow that path (Choose File> Export> Project as AAF file) there is none. All I can export to is:

-Export Region to Audio File

-Export Region to Loop Library

-Selection as MIDI file

What gives? How can I export something, following the directions LOGIC PRO 10 gives me, if I cannot even find the way to export it as the instructions say?

Please help me. I'm in dire straits.

Thanks
