I took out must the data and only have 2 survey stations and I get same error.  
Is there something wrong with this data?  Do I need to downgrade survex to 
make it work? 

---------- EG3.svx ------------
*begin EG3

*entrance A2

*units tape feet

*begin  ; Trip 1
*date 2004.07.04
*calibrate declination 7.55

*data normal from to compass tape clino 

;from   to      compass tape    clino
