Since you deleted the file that was causing the problem, we may never know. 
  My guess would be, since you were using a "lookup free", that something in 
the freechain was corrupted and pointed to a negative record number. 
(Though I haven't checked whether or not filePro would catch that and 
trigger a freechain rebuild.)
