ok, in case you are pointing to the right code, this crashes.

"fprintf(fi,"%d\r\n",max_record);"

is "fi" a valid file pointer... ? put after

fi = fopen("account.srt", "w+");

if(fi == NULL) perror("Error WTF!");


Looks like there is some lazy-ass code there, there is no error checking
whatsoever... ;-) and just seeing the firsts bits Im afraid it doesnt
quite do what you expect..

HTH.
