Doug,
What are you trying to send him? If I read the help on his site (hb9bza.net/lotw-users-list/8-lotw/3-lotw-how-to-help),
he wants one to generate an export from your LoTW account, not from LOGic. I just tried it and generated a 2MB file.
The export that LOGic has [Tools->Export log data->ADIF,...] also seems to work for me.
I'm running LOGic 9.0.84 on Windows 7.
Perhaps I just did not understand the question?
73s,
Don
