Cubase LE bundled with Lexicon Omega DRS

I’m trying to export audio tracks from this early version of LE (2005) - I want to mix the tracks down in Pro-Tools. The only ‘Export’ options under the file menu I find are ‘audio mixdown’ options - allowing me to export complete mixes in various formats (aiff, wav, etc.), but not, as far as I can tell, allowing me to export individual song tracks or a song project. The ‘Export’ page in my manual shows an entirely different window than the one that opens in my software. Am I missing some basic step(s)? Something obvious I don’t know? Is this not possible in this version? Any help will be appreciated. Thanks much.
