If you log into openflights you can import to there from flightmemory. Click on import and the directions should pop up. I believe it involves saving your flightmemory pages at html documents and importing those into openflights. It's a bit roundabout, and it's probably the easiest way since flight diary only takes csv files as imports and there's no real way to export flightmemory data as a csv. Considering that flight diary only lists two methods of imports if you check, there isn't really any other great options that I'm aware of.
