Error in PSAT software usage

I am research scholar from India. I am using PSAT software for my research work. I had used the same software for my M.Tech project which worked very well at that time. Now I am coming across following error when I load data file and run power flow.

Newton-Raphson Method for Power Flow Computation Data file "C:\Users\EXAM\Desktop\MANJULA\example1(mdl)" Writing file "fm_call" ... ??? Error using ==> fprintf Invalid file identifier. Use fopen to generate a valid file identifier. Error in ==> fm_wcall at 49 count = fprintf(fid,'function fm_call(flag)\n\n');

Error in ==> fm_spf at 41 fm_wcall;

Error in ==> fm_set at 720 fm_spf
