I have a question about WASP linkage from EFDC. When I try to use a hydrodynamic linkage file named “*.hyd” which was produced by EFDC Explorer it always pops up a dialog box saying “abnormal program termination” and after pressing OK,then WASP will automatically close. Can you tell me why it is ? Someone told me it is because my WASP is version7.3, is that true? Can you give me some suggestions? Thank you very much.
