It happened again

Over the weekend, I was using Beersmith2 on my laptop (which runs Win 7 and is on a wireless network). I recieved the following errors:
7:22:07 AM: Write error on file '\\D9200\BeerSmith2\JS-Data/T-6399Recipe.bsmx' (error 64: the specified network name is no longer available.)
7:22:07 AM: Write error on file '\\D9200\BeerSmith2\JS-Data/T-6399Recipe.bsmx' (error 64: the specified network name is no longer available.)
7:22:07 AM: Write error on file '\\D9200\BeerSmith2\JS-Data/T-6399Recipe.bsmx' (error 64: the specified network name is no longer available.)
7:22:07 AM: failed to flush the file '\\D9200\BeerSmith2\JS-Data/T-6399Recipe.bsmx' (error 64: the specified network name is no longer available.)
The first error appeared dozens and dozens of times. The last one only appeared once.
I reopened beersmith on this machine and used it thoroughly and everything appeared to be fine.
However, then a few days later, I opened beersmith on the hosting machine (a win XP desktop which is connected to the same network via ethernet), and saw all my recipes were gone other than ones from 2006 and 2005!
I run Beersmith.exe from \\D9200\BeerSmith2\BeerSmith2.exe
my data directory is \\D9200\BeerSmith2\JS-Data
I am going to continue to monitor this and see if I can identify a pattern. Any information you might have about the error above would help.
