I hope your 48 has gotten ahold of itself by now, but this brings up  
a good point Bill Wickes mentions in HP48 Insights.....
  
If the 48 has a cardiac arrest resulting in the "Try to Recover Memory"
message, and if you reply [YES], it scans through memory trying to 
reconstruct your HOME directory and all its subdirectories (except the
"hidden directory" containing the alarms and key assignments, which are
supposedly always lost -- although I've sometimes found them stuck in
other directories) and port 0.  If the 48 finds a library, it assumes
that is the start of port 0 (well, for the first library it finds, anyway).
If you had a library stored in a global variable and the 48 finds it when
attempting to recover memory, it will forget about restoring any more of your
VAR memory, so that the rest will likely be lost.
  
The moral, try not to keep libraries stored in global variables.
