Are you from Philippines? If you are, get a legitimate copy of your GE-Survey from Engr. Elmer Robles he is the one who made that Surveying software. actually there's a way not to encounter that kind of problem but I am sorry I think your sofware is pirated.
He put something in his program that detect the current date. Very clever guy. If you are a lisp user like me you can change it and adjust it.
