GASP problem

Rothan

I am developing a 3D N-S code and meanwhile use GASP for validation. I met a problem which did not appear when I was in the stage of working on 3D Euler. When I open "front" window and finish all the input work, then I turn to save the file in local directory. GASP always told me that the file already exists and asked me whether I want to overwrite it or cancel. Actually there is no file with same name in my working directory. If I choose save, after a while the "front" window closed and a message of " can not open (here is my working directory)../../database/db1.bin" appears. I can make sure the chemistry database file db1.bin exists and I already enter the correct path to it in "front" window. Thus I am puzzled about this. Could anyone familiar with GASP give me some advice? Thanks.
