Thanks Mel I've learned a hard lesson.
Looks like I lost 48 hours worth of QSO's because I logged in QSL's 
on the office computer which updated the station machine with an earlier copy.

Before I just copied the n2la.dxl file over the network to the office machine but made _all_
changes on the station machine - I'll do that in the future.

The only reason I did it is so spots would be updated with the latest log information.
But I now see it's just too dangereous to use the station log in the office computer over the network
because a single mis-step would cause the station computer to get a "stale" update.
Never again!
