Save the Finale file as a midi file, then import/open the midi file in Logic. You may be able to save the entire Finale score and/or individual staves as audio files/tracks and the import them into Logic. I've not worked this method, just the midi method, nor have I tried saving a Windows Finale file and then moved it to Logic (Mac only).
Beyond these suggestions, I can't provide any further help.
